Question

Calculate the size of lettered angle in the figure.​

Answer 1

Step-by-step explanation:

as the left triangle is isosceles, there are two 35 degree angles. the third one is 180-(35+35)= 180-70= 110

y+110= 180

y=70

x= y+35(sum of the two interior angles is equal to the opposite exterior angle)

x=70+35

x=105 degree
