Question

two complementary angle are
(x+4) ° and (2x-7) find the value of x

Answer 1

the angles are complementary

so

(x+4) = 90 - (2x-7)

x + 4 = 97 - 2x

3x = 93

x = 31

Answer 2

as they are complementary

x+4+2x-7=90
3x-3=90
3 x=93
x=93/3=31 degree.

so the angles are

x+4=35 degree

2x-7=(31×2)-7
=62-7=55 degree

hope this helps
