In triangle bcd if bc =bd angle b = 13x-35 angle c =5x-19 and angled d = 2x+14 find x and the measure of each angle
Answers
Answer:
<b = 108 degrees
<c = 36 degrees
<d = 36 degrees
Step-by-step explanation:
The sum of angle in a triangle is 180 degrees
Hence <b + <c + <d = 180
13x-35 + 5x - 19 + 2x + 14 = 180
13x+5x+2x-35-19+14 = 180
20x-40 = 180
20x = 180 + 40
20 x = 220
x = 220/20
x = 11
Get <b
<b = 13x-35
<b = 13(11) - 35
<b = 143-35
<b = 108 degrees
Get <c
c =5x-19
<c = 5(11)-19
<c = 55-19
<c = 36degrees
Get <d
<d = 2x+14
<d = 2(11) + 14
<d = 22+14
<d = 36 degrees

help
Answers
Answer:
The division was incorrectly solved.
Step-by-step explanation:
Given
[tex]\frac{2}{5} / \frac{8}{9} =\frac{5}{2} * \frac{8}{9} =\frac{5*8}{2*9} = \frac{20}{9}[/tex]
Required
Explain why it is wrong
The solution is wrong because the division was incorrectly solved.
When fraction a/b is divided by c/d, the solution is:
[tex]\frac{a}{b}/\frac{c}{d} = \frac{a}{b} * \frac{d}{c}[/tex]
It should be noted that:
[tex]\frac{a}{b}/\frac{c}{d} \ne \frac{b}{a} * \frac{c}{d}[/tex]
The solution to the quotient is:
[tex]\frac{2}{5} / \frac{8}{9} =\frac{2}{5} * \frac{9}{8} =\frac{2*9}{5*8} = \frac{9}{20}[/tex]

Which ordered pair is a solution of the equation?
y = -2x+ 5
Choose 1 answer:
a.Only (2, -9)
b.Only (-2,9)
c.both (2, -9) and (-2,9)
d.neither
Answers
Answer:
Only (-2, 9) is the solution of the equation.
Hence, option 'b' is correct.
Step-by-step explanation:
Given the equation
y = -2x+ 5
Checking the ordered pair (2, -9)
substituting x = 2 and y = -9 in the equation
y = -2x + 5
-9 = -2(2) + 5
-9 = -4 + 5
-9 = 1
FALSE!
L.H.S ≠ R.H.S
Thus, the ordered pair (2, -9) is NOT a solution of the equation.
Checking the ordered pair (-2, 9)
substituting x = -2 and y = 9 in the equation
y = -2x + 5
9 = -2(-2) + 5
9 = 4 + 5
9 = 9
TRUE!
L.H.S = R.H.S
Thus, the ordered pair (-2, 9) is a solution of the equation.
Conclusion:
Only (-2, 9) is the solution of the equation.
Hence, option 'b' is correct.

It must be 2:3 so you have to change the current ratio from black to white(7:8) to 2:3
So the first number has to be the closets multiple of 2(8) and you have to divide 8 by 2 to get 4 and multiply that by 3 to get the ratio 8:12 which is equivalent to 2:3

Answer:
(7,12),(-12,-7)
Step-by-step explanation:
x^2 + y^2 = 193
x - y = - 5
x = y - 5
(y - 5)^2 + y^2 = 193
y^2 - 10y + 25 + y^2 = 193
2y^2 - 10y + 25 = 193
2y^2 - 10y + 25 - 193 = 0
2y^2 - 10y - 168 = 0
2*(y^2 - 5y - 84) = 0 This factors into
2*( y - 12) (y + 7) = 0
y = 12
in which case x = 12 - 5 = 7
y = - 7
in which case x = -7 - 5 = - 12
