Answer: To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

Answer:
Step-by-step explanation:
g(2) = 3(2) - 3 = 6 - 3 = 3
h(3) = 3^2 - 4(3) = 9 - 12 = -3
A is the answer
The matchings are as follows:
1) 2=3 , 4 =5 (Given)
2) 1 =3 (vertical angles are equal)
3) 1 =2 (substitution)
4) VR=VR (Reflexive)
5) Triangle VSR congruent to Triangle VTR (ASA)
6) RS=RT CPCTE
The matchings are done above. The triangles are congruent as per ASA congruency as two angles and corresponding side is equal.
since 2 =3 and 1 = 3 we get 1=2
By CPCTE we have RS =RT
