What is the value of x? X=32 X=36 X=37 X=40

Answer: x = 40

Step-by-step explanation:

Always when you have a line and another line that cuts it, two consecutive angles always add up to 180° (the plane angle)

Then, in this case we can see that:

x + (4*x - 20) = 180

for the internal angle of the right and the external one.

now, we can solve this equation for x.

x + 4*x - 20 = 180

5*x = 180 + 20 = 200

x = 200/5 = 40

A line is 180 degrees so write x+(4x-20)=180

A and B are complementary angles. If A = (x – 23)° and m
Lana71 [14]

Answer:

∠ B = 85°

Step-by-step explanation:

Complementary angles sum to 90° , then

x - 23 + 2x + 29 = 90 , that is

3x + 6 = 90 ( subtract 6 from both sides )

3x = 84 ( divide both sides by 3 )

x = 28

Then

∠ B = 2x + 29 = 2(28) + 29 = 56 + 29 = 85°
