Question

(v). What is the relation between y and z.
(a). 2y + z = 90°
(b). 2y + z = 180°
(c). 4y + 2z = 120°
(d). y = 22
​

Answer 1

you have to cross multiply..

Explanation:

Y is given 22 at the last option..so, @2y +z =90°= 2×22+z =90.

44+z=90

z=90-44=46..

b. 2×22+z=180 ( y is 22)

44+z=180

z=180-44=136.

c. 4×22+2z=120

88+2z=120

2z=120-88=32

z=32/2= 16.

d. y= 22 given
