Question

x,y and z are three angels on a straight line if x=y=z find value of z

Answer 1

Answer:

x,y,z are on straight

x+y+z= 180

here. x=y=z

therefore

z+z+z = 180

3z=180

z=180÷3

z=60°

Answer 2

Answer:

straight lines makes always straight angles

straight angle =180°

ATQ

x,y and z lies in the straight line

so the sum of these 3 angles will make 180°

so

$x + y + z = 180 \\ z + z + z = 180 \\ 3z = 180 \\ z = \frac{180}{3} \\ z = 60$

( as x=y=z so all the three angles are taken as z in step 2 )

.•. x=y=z = 60°

so the angle of z is 60°
