Find the missing length of the triangle.
26 in.
a
24 in.

Work Shown:

Apply the pythagorean theorem to get...

a^2 + b^2 = c^2

a^2 + 24^2 = 26^2

a^2 + 576 = 676

a^2 = 676 - 576

a^2 = 100

a = sqrt(100)

a = 10

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
