Answer:

Step-by-step explanation:

this is a really questuon so instead of x we put -3 so its going to look something like this. (PLUG IN -3 FOR X)

f(-3)= (-3)^2+6

f(-3)= -9+6 (-9 because of -3^2)

then the equation becomes

f(-3)= -9+6

(USING THE RULES) we get -3 as our Final answer

Statement ∠T and ∠S are complementary ∠S and ∠U are complementary m∠T+m∠S=90 m∠S+m∠U=90 m∠T+m∠S=m∠S+m∠U m∠U=m∠T ∠U≅∠T

Leto [7]

Answer:

See Explanation

Step-by-step explanation:

According to the Question,

Given That, ∠T and ∠S are complementary & ∠S and ∠U are complementary

Thus, m∠T + m∠S = 90 ------ Equation 1

& m∠S + m∠U = 90 ------- Equation 2

Now, Subtract Equation 2 From Equation 1, we get

m∠T - m∠U = 0

Thus, m∠T = m∠U

The measure of angle T is equal to angle U.(∠U≅∠T).
