In each figure below, find m1 and m2 if a||b. Show your work with statements.

Sladkaya [172]

Answer:

∠ 1 = 130°, ∠ 2 = 50°

Step-by-step explanation:

∠ 1 and 130° are alternate angles and congruent, so

∠ 1 = 130°

∠ 2 and 130° are same- side interior angles and are supplementary, so

∠ 2 + 130° = 180° ( subtract 130° from both sides )

∠ 2 = 50°

Does there exist 2 distinct prime numbers such that their product is a square number?

satela [25.4K]

Answer:

NO.

Step-by-step explanation:

If the 2 prime numbers are odd then the product cannot be a square number because the only factors are the original prime numbers. If one of the prime numbers is 2 then the product will be an even number , but again the only factors will be 2 and the other prime number.

So the answer is No.
