Question

help me @ksanka

Answer 1

Angle Q + Angle R = Angle T

Answer 2

the sum of angles Q and R is equal to angle T.
127=63+Q
Q=64

Answer 3

An exterior angle of a triangle is equal to the sum of the two interior angles that are not adjacent to that exterior angle.

In this case, T is an exterior angle of the triangle, and Q and R are the two interior angles that are not adjacent to T.

So, the measure of T is equal to the sum of the measure of Q and the measure of R.

mT = mQ + mR
127° = mQ + 63°
64° = mQ

Therefore, mQ is 64°.

Answer 4

yes that's right

Answer 5

@ksanka that is the explanation that is given when they put in the answer as 64 in case they wanted to know why :P

Answer 6

That is the way how Study Island works lol :P
