In the figure below, =m∠2=134°. Find m∠1.

46

Step-by-step explanation:

a straight angle is 180 degrees

it is given that angle 2 is 134 degrees

Angle 1 and 2 will add up to 180

180-134=46

(can I get brainliest please)

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.
