Two supplementary angles are in the ratio 2:7. Find the measure of the Acute angle.

Answers

Answer 1

Answer:

y=42.3333333333 (repeating)

Step-by-step explanation:

You need to find the corresponding side. You can see D H is corresponding to E C. So here is what you have to do, find x to (8x - 43) and (2x + 13).

2x + 13 + 8x - 43= 90

10x -30 = 90

+30 +30

10x = 120

/10 /10 = 12

to check if this is right take x which is 12 and plug it in.

8 x 12= 96 then 96 - 43= 53

2 x 21= 24 then 24 + 13= 37

Next you take 53 and 37 and add it together

53 + 37= 90

about that corresponding side, now you know D H and E C both equal 53

Now you can solve your equation.

53 + 2y + y= 180

53 + 3y = 180

-53 -53

3y = 127

/3 /3

y = 42.333333 (repeating)

to check if this is right take y which is 42.3333333 (repeating) and plug it in.

2y means to multiply y two times so...

42.3333333 (repeating)+ 42.33333333 (repeating)= 84.6666666 (repeating)

y = 42.333333333 (repeating)

E C = 53

add all the numbers together

42.333333 (repeating) + 84.66666666 (repating)+ 53= 180

Therefore y equals 42.33333333 (repeating)

Answer:

x=15

Step-by-step explanation:

4 I x-5 I +20 = 60 Distribute the 4

4x - 20 + 20 = 60 Combine like terms :

4x - 0 = 60

4x = 60 Divide:

x = 15

Check : 4 I 15 - 5 I + 20 = 60

4 I10I +20 = 60

40 + 20 = 60

60 = 60 ✔

2. Which part of the triangle is always directly
opposite the right angle?

Answers

Answer:

So BASically

A triangle has 3 sides

One is the hypotenuese

The other is the Base

and the last one is perpendicular

Step-by-step explanation:directly

opposite the right angle is The HYPOTENUESE

Answer: Hypotenuse

For any triangle, the longest side is always opposite the largest angle. The largest angle of a right triangle is always the 90 degree angle. If you had any larger angle, then the triangle wouldn't be a right triangle and instead it would be obtuse.

In a right triangle, the longest side is given the special name hypotenuse. The other sides of a right triangle are called the legs.

Step-by-step explanation:

For this problem, we know that A is the correct answer. A is the same as the given expression because it is the same, but the order is switched. When you multiply both of them, you would get the same answer.

We can eliminate B because [tex]\frac{2}{5}[/tex] should be positive, not negative.

We can eliminate C because the fraction should be [tex]\frac{2}{5}[/tex], not [tex]\frac{5}{2}[/tex].

We can eliminate D because (-1×-7) given you 7, not -7.

Therefore, A is the right answer.

Answer:

3^8 and 6,561

Step-by-step explanation:

1) Calculate, 3 to the power of what is 27?

Make a table of all of 3's powers until 10. i.e. 3^1 = 3, 3^2 = 9 ......

You will find that 3^3 = 27 and 3^5 is 243

3) Use the formula x^m * x^n = x^m+n and substitue our value.

It should look like this: 3^3 * 3^5 = 3^3+5 = 3^8

4) Make a table as described in step 2 and calculate all of 3's powers up to 10. Look at your table and you will find that 3^8 is equal to 6,561

5) The expression written as a power is

3^8 and

the value: 6,561
