ABC congruent DEF find the measure of the given angles or the lengths of the given sides

Answers

Answer:

BC = 8 and EF = 8

Step-by-step explanation:

Congruent triangles have equal angles, equal sides, equal perimeters, and equal areas.

Let us solve the question

∵ The two triangles ABC and DEF are congruent

∴ BC = EF

∵ BC = 3z + 2

∵ EF = z + 6

→ Equate their length

∴ 3z + 2 = z + 6

→ Subtract z from both sides

∵ 3z - z + 2 = z - z + 6

∴ 2z + 2 = 6

→ Subtract 2 from both sides

∵ 2z + 2 - 2 = 6 - 2

∴ 2z = 4

→ Divide both sides by 2

∴ z = 2

→ Substitute z by 2 in the length of sides BC and EF to find them

∵ BC = 3(2) + 2 = 6 + 2

∴ BC = 8

∵ EF = 2 + 6

∴ EF = 8

Can anyone help me I want to copy the answer down so I know how to solve it❤️

Answer:

t = 4°

Step-by-step explanation:

As in any triangle, the sum of angles is 180°.

17t + 16t + 12t = 180°

45t = 180° . . . . . collect terms

t = (180/45)° . . . . divide by the coefficient of t

t = 4°

What type of equations could have extraneous solutions?

Answers

Answer:

Step-by-step explanation:

The square root equations could have extraneous solutions.

What is an extraneous solution?

An extraneous solution is a “false” solution to an equation. An extraneous solution does not satisfy the original equation, even though we took seemingly valid steps while solving the equation.

When we solve an equation with containing a radical expression, we have to isolate the radical on one side from all other terms and then square both sides of the equation.

When we square a radical equation we sometimes get a solution to the squared equation that is not a solution to the original equation. Such an equation is called an extraneous solution.

Hence, the square root equations could have extraneous solutions.

Which graph has an x-intercept of -2 and a y-intercept of 4?

Answers

Answer:

The first graph

Step-by-step explanation:

the first graph crosses through -2 on the x-axis and 4 on the y-axis

The required graph that shows an x-intercept of -2 and a y-intercept of 4 is graph A. Option A is correct.

What is the intercept in the equation?

In the equation intercept is the value of the linear function where either of the variables is zero.

Here,
X intercept is the value of the line where y ordinate is zero, from observation it is found that graph A has x intercept of -2 and y-intercept of 4.

Thus, the required graph that shows an x-intercept of -2 and a y-intercept of 4 is graph A. Option A is correct.

The possible combination of sides of triangles is

(2 + 3) >4(3 + 4)> 5(5+ 6)>7What is Property of Triangle?

In a triangle, the third side must be greater than or equal to the sum of the other two sides. The length of a triangle's third side is always longer than the sum of any two of its sides.

Given sides are 2 inches, 3 inches, 4 inches, 5 inches, 6 inches, and 7 inches.

We know that the third side of a triangle is greater than sum of other two sides.

So, (2 + 3) >4

and, (3 + 4)> 5

and, (5+ 6)>7

Hence, the possible combination of sides of triangles is

(2 + 3) >4(3 + 4)> 5(5+ 6)>7

Answer:

A. trapezoid

Step-by-step explanation:

The missing angle U is 86°, the value that makes the total be 360°. Then the top two angles total 180°, as do the bottom two angles. This means sides SV and TU are parallel, but sides UV and ST are not.

The figure has one pair of parallel sides, so is a trapezoid.

7 1/2 is equal to _____ in radical form?

Answers

Answer:

√ 7

.........................

7 1/2 in radical form is √15 / √2 x √15 / √2.

To convert the mixed number 7 1/2 to radical form, we need to rewrite it as an improper fraction and then simplify.

First, let's convert the mixed number to an improper fraction:

7 1/2 = (2 x 7 + 1)/2 = 15/2

Next, we can represent 15/2 in radical form by taking the square root of the numerator and the denominator separately:

√(15/2)² = √15 / √2 x √15 / √2

The square root of 15 cannot be simplified further, so we leave it as √15.

Therefore, 7 1/2 in radical form is √15 / √2 x √15 / √2.

254/2 because 2/3 of the students is 254 and this is to simplify it

127*3 because 127 is 1/3 of the total number of students so 127*3 would be 3/3 of the students or all of them

381+1 because we had to take out 1 of the students because there was an aditional vote so we add him back in
