I got 14 and 12 but there are other answers as well.
How I got that: I worked backwards. I looked at what two values I could multiply to get 4x^2 and because 4x^2 is a perfect square I just went with the square root (2x). Then I looked at what two pairs I could multiply to get 12 and I went with 3x4 and 6x2. I then plopped those numbers into binomials [(2x+3)(2x+4) and (2x+2)(2x+6)] and simplified (multiplied them) to get the middle value. (I hope this helps)

∠1 and ∠2 are supplementary angles. If m∠1 = 77°, then m∠2 =

posledela

Answer:

B. 103°

Step-by-step explanation:

Supplementary angles add up to 180°, so we can find the measure of angle 2 by subtracting 77 from 180

180 - 77

= 103

So, m∠2 is 103°

Find the value of the variable and YZ if Y is between X and Z

PIT_PIT [208]

If point Y is between points X and Z, then

XY + YZ = XZ

In words, the distance from X to Y, plus the distance from Y to Z, is equal to the distance from X to Z. (See the attached picture.)

So 6b + 8b = 175
