Answer:

x = 60

Step-by-step explanation:

Since the 3 sides of the triangle are congruent, then the triangle is equilateral with interior angles congruent and equal to 60°

x and the angle on the right of the triangle are alternate and congruent, so

x = 60

Answer:

1) 5 2) 6 3) 1.25 or -1.75

Step-by-step explanation:

1. x^2 - 25 = 0

x^2 - 25 = 0

First, add 25 to both sides!

x^2 = 25

Now square root both sides.

x = 5

2. (x-2)^2 = 16

First, square root both sides.

(x-2) = 4

Add 2 on both sides.

(x) = 6

x = 6

3. Quadratic Formula = -b ± $\sqrt{b^{2}-4ac }$ / 2a

Substitute in:

-6 ± $\sqrt{7^{2} -4(2)(6)}$ / 2(2)

-6± $\sqrt{49 - 48}$ / 4

Both forms:

-6 + $\sqrt{1}$ / 4

5 / 4 = 1.25

Negative:

-6 - 1 / 4

-7 / 4 = -1.75
