Question

Help!! One angle of a triangle measures 65º. The side opposite this angle has length 10. If the area of the triangle is 20, find the perimeter.

Answer 1

This one will likely require collecting all the equations you know about a triangle and its area/angles/perimeter and solve the long way.

Answer 2

Do you know what type of triangle, such as right or equilateral? That would help a lot.

Answer 3

it was not given the type of triangle.

Answer 4

is there a picture to go with it?

Answer 5

no :(

Answer 6

Hmm. A = 1/2bh
20 = 1/2bh
20 = 1/2 (10)h

Answer 7

The answer is perimeter=25, but I do not know how to get to this answer.

Answer 8

Solve for h then you will have 2 numbers toward the perimeter

Answer 9

That's really helpful! So whatever number you get for h. Do 25 - 10 - h

Answer 10

I tried doing it that way, but assumes that it is either a right or isosceles triangle. And I did not arrive at the answer, perimeter=25.

Answer 11

For this problem I have to show my work towards the answer of perimeter=25. That information is not given in the problem.

Answer 12

25 - 10 - 4 = 11 is what I got

Answer 13

Okay, thank you for trying to help me. I will have to ask my teacher tomorrow.
