Question

12. Find the measure of unknown angles in the given figure.

PLZ ONLY WRITE IF YOU KNOW THE ANSWER

Answer 1

Answer:

ac= 4 because ac=1/2 of ab and cb and a is 85 and b is 1/2 of 85 I.e 42.5

Answer 2

Answer:

This is an isoscales triangle.........( any two sides of isoscales triangle are congruent.)

angles opposite to congruent sides are also congruent .

so,

angle a = 85°

and

sum of all angles of a triangle is 180°

there fore,

85 +85 + b = 180

170 + b = 180

b = 180 - 170

= 10

angle b = 10 °

by these steps we can find measure of unknown angles...

hope it will help you.....☺️
