Step-by-step explanation:

9x+6+5x+90°= 180°

14x+96=180

14x=180-96

14x=84

x= 84/14

x=6

so, <A=5x=5(6)=30°

<B=9x+6=9(6)+6=54+6=60°

<C = 180-(30+60)=180-90=90°

Given that cos 63°≈ 0.454, enter the sine of a complementary angle. sin

jek_recluse [69]

Answer:

$\cos(63^\circ)$ is the same as $\sin(27^\circ)$ by co-function identities

Step-by-step explanation:

Remember that complementary angles add up to 90°. The angle that i s complementary to 63° is 27°.

Also recall the co-function identities:

sin (90° – x) = cos x
cos (90° – x) = sin x

This means that $\cos(90^\circ-27^\circ)=\sin(27^\circ)\approx0.454$ .
