Question

4. Calculate the size of each lettered angle in the following figures :
​

Answer 1

Answer:

x=32° (As in an isosceles triangle, angles opposite to equal sides are equal)

Let the third angle of the upper triangle be 1

then 32+32°+1=180°(Angle sum property)

64°+1=180°

angle 1=116°

116°+y=180° (Linear pair)

y=64°

angle 1 = z. (Alternate interior angles)

x=32°

y=64°

z=64°

Answer 2

Answer:

x=32 z=52 y=64 okkkkkkk
