Sure... a = tan(b) b+tan(a)=pi c = 45/sin(c*a*pi^2) solve all that and you get a=30, b=15, c=31

..... x+2x+2x+1=76 5x = 761 x=15 b= 15, a = 30, c = 31

i will solve it for you... a = tan(b) b+tan(a)=pi c = 45/sin(c*a*pi^2) a = tan(b) = sin(pi)+4 a = sin(pi) + 4 a = 30 b +tan(a) = pi tan(a) = pi  b b = pi^2 + 4 b = 15 c = a+1 c = 30 + 1 c = 31 does that make sense?

the first side of a triangle is 8 m shorter than the second side. the third side is 4 times as long as long as the first side. the perimeter is 26 m. find the length of each side.

a = cot(45)^2 + 30 a = pi^2  e^t + 30 a = 3 b = a^2 / cot(45) * pi^3 b = a^2  30 b = 11 c = b+a^4  n(4) c = b^2 2a c = 12 so the answer is a=3, b=11, c=12

you can check it's right because a+b+c=26

can u do it in another way
 2 years ago

ktklownBest ResponseYou've already chosen the best response.2
i can help you do it another way. call the first side "a", the second side "b" and the third side "c". it says "the first side is 8 meters shorter than the second side". can you write that as an equation?

I'm sorry nicki But I'm not going to help any more. You are not putting any effort into this at all. Like, 0 effort. You're just waiting for the answers so you can copy them down and turn them in.
