Question

Find the value of a witch angle (2x - 5) and (x-10) are the complimetary angle?​

Answer 1

Answer:

35°

Step-by-step explanation:

It is given that (2x - 5)° and (x - 10)° are the complementary angles.

We know that, if two angles are complementary, then their sum is 90°.

Then, (2x - 5)° + (x - 10)° = 90°

⇒ 2x - 5° + x - 10° = 90°

⇒ 3x - 15° = 90°

⇒ 3x = 105°

⇒ x = $\frac{105}{3}$

⇒ x = 35°

Therefore, the value of x for which the angles (2x - 5)° and (x - 10)°  are the complementary angles is 35°.
