Answers:

Angle A = 104 degrees

Angle B = 76 degrees

=================================

Supplementary angles add to 180 degrees.

A+B = 180

(3x-7)+(2x+2) = 180

5x-5 = 180

5x-5+5 = 180+5 ... add 5 to both sides

5x = 185

5x/5 = 185/5 .... divide both sides by 5

x = 37

Use x =37 to find

Angle A = 3x-7 = 3*37-7 = 111-7 = 104 degrees

Angle B = 2x+2 = 2*37+2 = 74+2 = 76 degrees

As a check: A+B = 104+76 = 180 so that helps confirm the answer

Find the perimeter of the triangle.

Rudiy27

Answer:

12 + 10 + 15,62= 37,62

Step-by-step explanation:

According to the Pythagorean Theorem, you will have this:

${a}^{2} + {b}^{2} = {c}^{2} \\ \\ {10}^{2} + {12}^{2} = {c}^{2} \\ \\ 244 = {c}^{2} \\ \\ 2\sqrt{61} = c \\ \\ 15,62049935 ≈ c \\ \\ 15,62 ≈ c \\ \\ 12 + 10 + 15,62 = 37,62$

* There was an error in the correct answer, so I corrected it, as you can see.
