Cos and sinc= yards rounded to nearest hundredth place

c = 8 yards

Work Shown:

cos(angle) = adjacent/hypotenuse

cos(45) = c/(8*sqrt(2))

c = 8*sqrt(2)*cos(45)

c = 8*sqrt(2)*(1/sqrt(2))

c = 8

Optionally, you can use the 45-45-90 triangle template which says that the length of the leg of this triangle is x and the hypotenuse is x*sqrt(2)

Since 8*sqrt(2) is the given hypotenuse, this must mean x*sqrt(2) = 8*sqrt(2) so x = 8

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
