Write about a real-life situation that could be described with the expression 1286 +953.

Julie wants to go to a theme park, so she starts a lemonade stand to make extra money. On Saturday, it's really hot, and several people buy lemonade, so she makes a total of $1,286. On Sunday, it's raining, so she only makes $953. How much money did Julie make from selling lemonade?

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
