Answer 1

Answer:

75 degrees

Step-by-step explanation:

3x = 90

x = 30

It is an isoceles triangle so each of the other angles = (180-30)/2 = 150/2 = 75

Answer 2

Answer:

Step-by-step explanation:

In triangle PQR

Angle QPR =180

Therefore, x+x+x =180

3x =180

x =180

Now,

In triangle PST

Since, triangle PST is an iscoceles triangle

Therefore, angle PST +angle PTS +30 degree =180 degree

Angle 2(PST) =180 -30. (ANGLE PST = ANGLE PTS)

ANGLE 2(PST) = 150

ANFLE PST = 75 degree
