Question

Find missing angles​

Answer 1

Answer:

x=y= 90

w=50

z=40

Step-by-step explanation:

For x and y

angle is 90 as angle in semi circle

angle w and z ... sum of angle of triangle is 180

Answer 2

Answer:

If any angle is formed from the centre it makes 90 degree

In tri ADC,

40 + W+ 90 = 180 ( triangle sum)

130 + w = 180

W = 50

In tri ABC,

Y = 90

Z + y + 50 = 180

Z + 90 + 50 = 180

Z= 40

X= 90, y= 90, w= 50, z = 40
