Please¡ can someone explain this? (27 + 15 : 3 + 8·(4 + 3) - 10=
(90 + 30) · 6 - 7 · 3 · 0 - (100 + 25) : 5=
(4 · 3 + 8 : 2) · 5 - (4 - 5) : 3=

answer: haha (: i’ll go see what it is

step-by-step explanation:

a

step-by-step explanation:

strong negative correlation

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.
