In triangle abc, find b, to the nearest degree, given a=7, b=10, and c is a right angle.

a. 35 degrees
b. 44 degrees
c. 46 degrees
d. 55 degrees

Option D is correct i.e angle B is 55°

Step-by-step explanation:

Given In triangle ABC,  a=7, b=10 and angle C is a right angle.

we have to find the angle B.

As given triangle is right angled triangle,

∴ we can apply the formula of trigonometric ratios to find the angle B

⇒

Hence, angle B is 55°

Option D is correct.
