Question

6.<A and < B are supplementary angles. If <A=30°, then <B is
a) 150°
b) 120°
c) 110°
d) 115°​

Answer 1

Answer:

120 is the answer of the question

Answer 2

Answer:

Option A - 150°

Step-by-step explanation:

Given:

• Angle A & B are supplementary.
• Angle A = 30°

To find:

• Angle B = ?

Solution:

》 Supplementary angles = Angles whose sum or addition gives 180°

So, here angle A + angle B = 180°

==> 30° + < B = 180°

==> < B = 180° - 30°

==> < B = 150°

Hence, angle B = 150° [ Option A]

Hope it helped you dear...
