∠B=68°

Step-by-step explanation:

We are given a right angled triangle ΔABC with ∠A=90°, AB = 7 and AC = 17.

as  ΔABC is a right angled triangle so we will use trignometric identity to find the measure of angle B.

with respect to ∠B we are given:

P=AC=17

and  B=AB=7

hence using the tangent trignometric identity we have:

Hence, to the nearest degree the measure of ∠B=68°
