Question

3. Find the angle measure x in this figure. PLZ GIVE ANSWER​

Answer 1

Answer:

in the given triangle 70+60+x +x=360

now you can see that there is 90 degree right angle

so it is  x+70+60+90=360

x+210=360

x=360-210

x=150

Step-by-step explanation:

Answer x=150

Answer 2

Answer is = 140°

Explanation:

Let Fourth angle of given quadrilateral be y.

We know that,

Sum of angles forms on a straight line is equal to 180°. This statement is also known as linear pair.

So,

→y + 90° = 180° [Linear pair]

→y = 180°-90°

→y = 90°

We also know that,

Sum of all interior angles of quadrilateral is 360°.

So,

→y+x+70° + 60° = 360° → 90° + x +130° = 360°

→x + 220° = 360°

→x=360° - 220°

→ x = 140°

Verification:

→y+x+130° = 360°

→ 90° + x + 130° = 360°

• Put x = 140°

→90° +140° +130° = 360°

→ 360° = 360°

Hence, Proved.

Therefore value of x is 140°
