Please can someone help me with this questions. find 40. Calculate the value of x in the figure below, 70° t ㅘ x . A. 90° C. 1700 B. 180° D. 550. 41. Find the value of y in the figure below, 42° 540 у A. 92° B. 42° C. 90° D 849​

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.

c

step-by-step explanation:

the answer is a.
