Question 4 (5 points)

9.8 ft

Step-by-step explanation:

Picture attached.

The side marked h is the side opposite the 55 degree angle.  The side marked 12 is the hypotenuse of the right triangle.  The trigonometric ratio that involves the opposite and hypotenuse is the sine.

Multiply both sides of the equation by 12 to get

Use a calculator (in degree mode!).

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
