On a coordinate plane, 3 triangles are shown. Triangle D E F has points (5, negative 2), (1, negative 2), (1, negative 4). Triangle D prime E prime F prime has points (2, 5), (2, 1), (4, 1). Triangle D double-prime E double-prime F double-prime has points (negative 3, 5), (negative 3, 1), (negative 1, 1). Which rule describes the composition of transformations that maps ΔDEF to ΔD''E''F''?

R0,90° ∘ T5,0(x, y)
T–5,0 ∘ R0,90°(x, y)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
