Question

What is the value of c? Please help me

Answer 1

c = 9.899

Explanation:

sin theta = opposite side/ hypotenuse

sin 45 = 7/c

Multiply each side by c

c sin 45 = 7/c *c

c sin 45 = 7

Divide by sin 45

c sin 45 /sin 45 = 7 /sin 45

c = 7 / sin 45

c=9.899494937

Rounding to the nearest thousandth

c = 9.899
