Question

PLSSS help!!!!!!!!!!!!!

Answer 1

y = 70°

x = 40°

Explanation:

• first of all, from the drawing, we understand that it is an isosceles triangle, 110 is an adjacent angle, we find the internal angle

180 - 110 = 70°

• the other angle at the base (y) is therefore congruent 70°, so we have the value of Y (70°)

• we know that the sum of the internal angles of a triangle is 180°, we remove the two congruent angles and we have x

180 - 70 - 70 =

40°
