Question

Q:5) of 2x-18°and 3*+68are complementos
angles. Find the value of x.
​

Answer 1

According to the problem, (2x - 7)° and (x + 4)°, are complementary angles’ so we get;

(2x - 7)° + (x + 4)° = 90°

or, 2x - 7° + x + 4° = 90°

or, 2x + x - 7° + 4° = 90°

or, 3x - 3° = 90°

or, 3x - 3° + 3° = 90° + 3°

or, 3x = 93°

or, x = 93°/3°

or, x = 31°

Therefore, the value of x = 31°.

Answer 2

Answer:

2x-18=3x+18

2x+3x=68-18

5x=50

X=5
