Find the angle of y dasdwadasdaw

C

Step-by-step explanation:

Since angles x and y lie on a single straight line,

∠x +∠y= 180° (adj. ∠s on a str. line)

Given that ∠x= 42°,

42° +∠y= 180°

∠y= 180° -42° (-42° on both sides)

∠y= 138° (simplify)

Thus, option C is correct.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

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.
