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:
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
