Question

Three lines meet at a point if the sum of
two of the angle formed is 15a°
the other angle is what is the answer

Answer 1

Answer:

Let the measure of the required angle be x°.

Then, measure of its complement =(90−x)°.

And, measure of its supplement=(180−x)°.

Therefore,

(180−x)=4(90−x)⇒180−x=360−4x⇒3x=180⇒x=60

Hence, the measure of the required angle is 60°.
