Question

Find m a 24.7
b 79.2
c 68.3
d 57.4
e 46.5
f 80.1
g 35.6

Answer 1

68.3 degrees

Explanation:

Since this is a right triangle, we can use trig functions

tan I = opp side / adj side

tan I = sqrt(82) / sqrt(13)

tan I = sqrt(82/13)

Taking the inverse tan of each side

tan ^-1 ( tan I) = tan ^-1( sqrt(82/13))

I = 68.2892

Rounding to the nearest tenth

I = 68.3 degrees
