Question

two complementory angles are (x+4)degree and (2x-7)degree find the value of x

Answer 1

Hi Friend !!

Here is ur answer !!!

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


3x - 3 = 90

x-1 = 90/3

x = 30+1

x = 31


Hope it helps u : )

Answer 2

Angles are :-
(x+4) & (2x-7)

We know that sum of complementary angle = 90°
So,

(x+4) + (2x-7) = 90°
x+4 + 2x - 7 = 90°
3x -3 = 90°
3x = 90+3
3x = 93°
x = 93/3
x = 31°

So the angles are:-
x +4 = 31+4
= 35°

&

2x-7 = 2(31) - 7
= 62-7
= 55°

Hope it helps.
