Answer:

61°

Step-by-step explanation:

Alright so the total amount of degrees in a 5-sided shape or pentagon is 540°. Since we have four of the five total angles, we can solve for the last one.

Sum of all the degrees of all five angles = 540°

The variable x is representing our last unknown degree.

90° + 107° + 144° + 138° + x° = 540°

Add up all the known degrees and solve for x.

479° + x° = 540°

Subtract 479 on both sides so that we can isolate x.

479° + x° - 479° = 540° - 479°

x° = 61°

So our final answer is 61°

Answer:

  5.  A) two solutions

  6.   one solution

Step-by-step explanation:

5. A graph shows the curve has two x-intercepts, so two solutions. You can also figure this by looking at the discriminant:

  b^2 -4ac = (7)^2 -4(-4)(8) . . . . a positive number

When the discriminant is positive, there are two real solutions.

__

6. The equation factors as ...

  0 = 3(x +3)^2

This will have one real solution at x=-3.
