Question

find the measure of the unknown angles in the following figure

solve this I mark u in brainlist​

Answer 1

Answer:

Since it is an isosceles triangle the base angle will be equal that is x= 75

Using angle sum property

75+75+y=180

150+y = 180

y = 30

Answer 2

Answer:

x°= 75°

y° = 30°

Step-by-step explanation:

In the above figure the triangle is isosceles triangle so,

x° = 75°

and

sum of measure of all angles in triangle is 180°

75+75+ y°= 180

150+ y =180

y° =180- 150

Y = 30°
