Tan100°=

1. tan80°
2. tan280°
3. -tan80°

  2.  tan 280°

  3.  -tan 80°

Step-by-step explanation:

Your calculator can help you figure this out.

The tangent function is periodic with a period of 180°, so tan(100°) will be equal to tan(100°+k·180°) for any integer k. Answer choices include k values of ±1, so two of them are correct:

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

lo.lll
