Answer: x = 5

Step-by-step explanation:

To solve -7(x-4) =63; first open the bracket

-7x + 28 = 63

Subtract 28 from both sides of the equation

7x = 63 - 28

7x = 35

Divide both sides by 7

x = 35/7

x = 5

-7(x-4) = 63. Divide each side by -7.

x - 4 = -9. Add 4 to each side.

x = -5

What is the length of AB ? Round to the nearest tenth.

Vinvika [58]

The only way you can find x here is to use a trig ratio. We have the reference angle of 75, CA is 10 which is the side adjacent to the reference angle, and we are looking for the hypotenuse. The ratio that relates the side adjacent to a reference angle to the hypotenuse is cosine. Therefore, $cos(75)= \frac{10}{x}$ . Solving for x we get $x= \frac{10}{cos(75)}$ . Do that on your calculator and find that the hypotenuse is 38.6 m long, last choice from above.
