What is the algebraic process of 2+30[-39(87)+3)

Follow PEMDAS

Step-by-step explanation:

-39(87) = -3393

-3393 + 3 = -3390

30(-3390) = -101700

2 + -101700 = -101698

101698 or -1.01698 x 10(5)

Step-by-step explanation:

2+30(-39x87+3)- multiply

2 + 30(-3393+3) - calculate the sum

2+30x(-3390) - multiply

2-101700 - calculate the difference

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.
