If a triangle has a 50 degree angle and a 60 degree angle, how many degrees is the third angle

Triangles angles always add up to be 180 degrees

So far you have 110 out of 180

180-110=770

The 3rd angle is 70 degrees

Hope this helps :)

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
