Question

In a ∆XYZ, the measure of X

is 30° is greater than the measure of Y is Z is a right angle.

Find the measure of Y .​

Answer 1

Step-by-step explanation:

since z is 90° and x is 30°

x+y+z=180°

90°+30°+y=180°

y=60°

Answer 2

Answer:

In ΔXYX

Step-by-step explanation:

<Y = a (let)

hence, <X = (a + 30)°

<Z = 90° (given)

so,

<X+<Y+<Z=180°

a+ (a+30) +90=180

a+a+30+90 = 180

2a + 120 = 180

2a = 180-120=60

2a = 60

a = 60/2

a = 30°

<Y = 30°
