Answer:

(5,10)

Step-by-step explanation:

(-10x + 7y = 20)8            -80x + 56y = 160

(8x - 6y = -20)10           + 80x - 60y = -200

                                                   -4y = -40

                                                       y = 10

Plug 1 in for y into the first equation

-10x + 7(10) = 20

-10x + 70 = 20

       - 70  - 70

-10x = -50

x = 5

Novosadov [1.4K]

Answer:

Step-by-step explanation:

From your choices, it looks like you want m<A

Solution

<C = 46°                      The triangle is isosceles. The two marked sides are equal.

<A + <B + <C = 180l    All triangles have interior angles = 180

<A + 46 + 46 = 180     Combine

<A + 92 = 180              Subtract 92

<A = 180 - 92

<A = 88
