a. Find the value of each variable to the nearest tenth.
b. Find the perimeter of the triangle to the nearest tenth.

(1 point)
a = 30, c = 36.6, perimeter = 87.6
a = 36.6, c = 30, perimeter = 87.6
a = 36.6, c = 17.2, perimeter = 74.8
a = 17.2, c = 36.6, perimeter = 74.8

P= a+b=c
So to find P we have to find a and c by using the Pythagorean theorem

anonymous · Answer

b is given as 21

anonymous · Answer

P=a+b+c sorry

anonymous · Answer

So nevermind the Pythagorean theorem lets solve for a and c using the formula. It would be easier

anonymous · Answer

I just lost myself, Im so sorry. Give me a sec to look over things.

@amistre64  Can you help her?

amistre64 · Answer

tan55 = a/21;  therefore a = 21 tan55

c = sqrt(a^2 + 21^2)

P = a+b+c

amistre64 · Answer

well, P = a+21+c  :)
