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:
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.....☺️
