Use the law of sines and/ or the law of cosines to solve each triangle round to the nearest tenths when necessary

measure of angle p

measure of angle q

measure of angle r

Part a) The measure of angle P is

Part b) The measure of angle R is

Part c) The measure of angle Q is

Step-by-step explanation:

step 1

Find the measure of angle P

Applying the law of cosines

we have

substitute

Step 2

Find the measure of angle R

Applying the law of sines

substitute the values and solve for sin(R)

we have

substitute

step 3

Find the measure of angle Q

we know that

The sum of the interior angles in a triangle must be equal to 180 degrees

so

substitute the values

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
