Question

HI GUYS



Solve plz................❤❤❤❤​

Answer 1

Answer:

x = 90°

y = 120°

z = 150°

Now ,

x + y + z = 90° + 120° + 150°

= 360° Ans...

Answer 2

Answer:

In the given ∆ the measure of third angle should be (180- 90+30)° = (180 - 120)° = 60°.

By exterior angle property we know that sum of two interior angles of a ∆ is equal to it's third's side exterior angle .

So , the measure of x =60+30=90°

Y = 90+30=120°.

Z = 90+60=150°

So x +y+z = 150 + 120 + 90 = 360°.
