Question

Find the value ~pic attached ​

Answer 1

Answer:

Y = 45°

A = 90°

Step-by-step explanation:

the sum of the interior angles is 180°, you have a 45° angle and 2 congruent side, so angle B = angle C, from the sign the angle A is 90°or you can do

180 - 45 - 45 = 90°

Answer 2

This is a isosceles triangle

Y value :-

• y = 45

x value :-

$= > \: x + 45 + 45 = 180 \\ = > x = 180 - (45 + 45) \\ = > \: x = 90 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$
