Answer:

5x - 1 = 3(x + 11)- Has one solution

4(x-2) + 4x = 8(x -9) 0- Has one solution

4(x - 6) + 4 = 2(x - 3)- Has one solution

2(x - 4) = 5(x - 3) + 3- Has one solution

2(x - 1) + 3.x = 5(x - 2) + 3- Has no solution

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