An angle that contains 126 degrees and 32 minutes is a(n) ____________ angle. A. right
B. acute
C. straight
D. obtuse

Answers

Answer:

option: D

Step-by-step explanation:

We are given one of the angle as 126 degrees and 32 minutes.

we know from the conversion of minutes to degrees that

1 minute=(1/60) degrees

so 32 minutes=(32/60) degrees=0.53333 degrees

Hence, 126 degrees and 32 minutes=(126+0.53333) degrees

                                                             =126.53333 degrees

" Obtuse Angle: An angle is said to be obtuse if it's measure is greater than 90 degree but less than 180 degrees" .

As the measure of the given angle is greater than 90° but less than 180°.

Hence, An angle that contains 126 degrees and 32 minutes is an OBTUSE angle.
An angle that is greater than 90° and less than 180° is an OBTUSE ∠.
Answer is D. Obtuse angle
