Step-by-step explanation:

<h3>#40</h3>

The triangle with angle x is isosceles as two sides marked as same.

The two angles opposite to equal sides measure x.

<u>Sum of interior angles of the triangle is:</u>

  • 100 + 2*x = 180
  • 2x = 180 - 100
  • 2x = 80
  • x = 40

TiliK225 [7]
Here you have a system of 2 equations and 2 unknowns. An easy way to solve this type is to isolate one of the variables.

12a + 2b = 8
2b = 8 - 12a
b =
b =  \frac{8 - 12a  }{2}
b = 4 - 6a

Now plug 4 - 6a into equation 1 to solve for a.

a + 5(4 - 6a) = 19

a + 20 - 30a = 19

-29a = -1

a = 1/29 (answer)

Now plug a into the equation for b

b= 4 - 6(1/29)

b= 110/29 (answer)
