The line shown has a slope of between point J and point L and between point R and point T. Which of the following best describes triangle JKL and triangle RST?
A.
The length of JL is equal to the length of RT.

B.
Triangle JKL is similar to triangle RST.

C.
Triangle JKL is congruent to triangle RST.

D.
The length of JK is equal to the length of RS.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

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.
