What is the relationship between the angle of depression of a person looking down from the top of a hill at their friend standing on the ground and the angle of elevation of the person on the ground looking up at their friend who is standing on top of the hill? a. the angle of elevation will be greater than the angle of depression because the person has to look up from the ground to see their friend at the top of the hill

b. The angle of depression and angle of elevation will add to 180°

c. The angle of depression and angle of elevation will be the same

d. The angle of depression would be greater than the angle of elevation because the hill is higher than the ground​

C) angle of depression and angle of elevation will be the same.

this is because the horizontal for angle of elevation and angle of depression are parallel

therefore, the two angles are same (alternate angles)

hope it helps.

pls mark brainliest !!!

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
