Angle A measures (x + 13) °. Angle B is complementary to angle A and measures (2x +23) °.
a. Write and solve an equation to find the value of x.
Not sure how to write the equation but the value of x = 18
b. What are the measures of angle a and angle b?
angle a = 31°
angle b = 59°

I just need help writing the equation, can someone help please?
Complementary means they add up to 90 degrees.
(x+13) + (2x+23) = 90
(x+13) + (2x+23) = 90
how did you get x without writing the equation? lol anyway
90=2x+23+x+13
90=3x+36
54=3x
18=x
90=2x+23+x+13
90=3x+36
54=3x
18=x
34
Looks good (x+13) + (2x+23) = 90
What I do first may be different from what other people do first but what I do
first is combine like terms 3x+36. 90-36=54. Then, 3x/3 54/3 x=18. Then take the original equation (x+13) + (2x+23) = 90 and make the x's 18. (18+13) + (36+23) = 90
Angle A: 31
Angle B: 59
