Janet is designing a frame for a client. She wants to prove to her client that m angle1=m angle3 in her sketch What is the missing justification in the proof?

A. Definition of Supplementary Angles

B. Intersecting Lines Postulate

C. Same-Side Interior Angles Theorem

D. Vertical Angles Theorem

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.

20

step-by-step explanation:

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
