Question

in figure if poq is a line then the largest angle is​

Answer 1

Answer:

largest angle is 105 degree

Step-by-step explanation:

30+7x+3x=180

x=15

7*15=105

Answer 2

Given:

PQ is a straight line

∠POC = 30°

∠COD = 7x

∠QOD = 3x

To find:

the largest angle

Solution:

In the given statement, PQ is a straight line.

Hence, the sum of all the angles formed at a point is 180°.

So, we can write,

30° +$7x+3x=180$°

⇒$10x=150$°

⇒$x=15$°

Therefore, respective angles are:

∠COD = 7x

=105°

∠QOD = 3x

=45°

Hence, the largest angle is ∠COD = 105°. (Option b)
