A man spend 24% of his salary on transportation,25% of the rest on rent and the balance left is 1710 how much was spent on the rent​

About, 492.63.

Step-by-step explanation:

X(.76)(.75) = 1170

X = 1170/(.76)(.75) = about 2052.63

Spent on Transportation is the original amount * .24 = .24*1170/(.75 * .76) = around 492.63.

irrational, cannot

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.
