complementary angle.
angle 1: 26
angle 2:5x
what is the value of x?
a.12.8
b.64
c.30.8
d.26
To find the complementary angle, we need to add the measures of angle 1 and angle 2 and set it equal to 90 degrees.
26 + 5x = 90
Subtract 26 from both sides:
5x = 90 - 26
Simplify:
5x = 64
Divide both sides by 5:
x = 64/5
x ≈ 12.8
So the value of x is approximately 12.8.
The answer is: a. 12.8
