Answer:

38.5°

Step-by-step explanation:

You are given all three side lengths of the relevant triangle, so the Law of Cosines can be used to find any desired angle. If we call the desired angle C, then that law tells you ...

C = arccos((a² +b² -c²)/(2ab))

where a and b are the triangle side lengths adjacent to the angle of interest, and c is the side opposite. Here, 'a' and 'b' are the pole and cable lengths, and 'c' is the distance of the stake from the pole.

C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360)

C ≈ 38.515°

The cable makes an angle of about 38.5° with the pole.

Sweatshirt = $32 t-shirts = $14 ,

rodikova [14]

Cost of a sweatshirt = $32
Then
Cost of 14 sweatshirts = (32 * 14) dollars
= 448 dollars
Cost of a t-shirt = $14
Cost of 32 t-shirts = (32 * 14) dollars
= 448 dollars
So it can seen from the deduction that the cost of 14 sweatshirts and 32 t-shirts comes out to be same and equal to $448. I hope the answer and the procedure of doing this problem is clear to you. It is important to look at all the details given in the question and then start solving the problem.

Find (−3d2+10d−8)−(7d2−d−6). The difference is .

katovenus [111]

-10d^2 + 11d - 2

To find this, distribute the - to 7d^2 - d - 6.

This will give you a new equation of:

-3d^2 + 10d - 8 -7d^2 + d + 6

Combine like terms to get the answer above.

Hope this helps!
