Question

Find the measure of each angle to the nearest tenth of a degree.

a) sin A=0.2345
b) cos B=0.8765
c) tan C= 1.2345

Answer 1

To find the measure of each angle, use inverse trigonometric functions. For sin A=0.2345, use sin^-1(0.2345) to find the angle measure. For cos B=0.8765, use cos^-1(0.8765) to find the angle measure. For tan C=1.2345, use tan^-1(1.2345) to find the angle measure.

Step-by-step explanation:

To find the measure of each angle, you can use inverse trigonometric functions.

For part (a):

sin-1(0.2345) = 13.4 degrees (approximately)

For part (b):

cos-1(0.8765) = 29.3 degrees (approximately)

For part (c):

tan-1(1.2345) = 49.4 degrees (approximately)
