Answer: 5.4
Step-by-step explanation:
Use cosine to find the adjacent side.
cosine = adjacent/hypotenuse
Substitute these values in the cosine equation:
cos(39) = x/7
7*cos(39) = x
Use a calculator to find the value of x:
x = 5.4
The given product is

We have to use the distributive property

Then, we reduce like terms

<h2>Hence, the answer is A.</h2>
<span>Hello :)
6(x+3)=(x+3)+(x+3)+(x+3)+(x+3)+(x+3)+(x+3)
Six times some number plus 3 is 42.</span>
i think it’s perpendicular
3/5 *45/A is the equation
therefore A would equal 5*15
which is then be 75 inches
