Question

pls answer the question with explanation​

Answer 1

Answer:

angle x=120°, angle y=40 , and angle=20°

So, we have to add all angle

angle x+ angle y+ angle z

120°+40°+20°=180°

So, the answer is straight angle

because straight angle=180°

And it is also 180°

Answer 2

It is called a :-

b) Straight .

Explanation :-

Total angle formed = Angle X + Angle Y + Angle Z = 120+40+20°

So, 180°

Now,

Right angle = 90°

Straight Angle = 180°

Obtuse Angle = Greater than 90° but less than 180°

Acute angle = Less than 89° but greater than 0°

.

So only one angle meets the circumstances.i.e,

Straight Angle .

So, b) Straight is the correct .

Hope it helps friend !
