Answer:

Your answer would be 2

Step-by-step explanation:

15 - 6(x+1) =12

15- 6*x +6*1 = 12

15 - 6x + 6 = 12

15 - 6 + 6x = 12

9 + 6x = 12

9 - 9 + 6x = 12 - 9

6x = 3

x = 2

Solve: 2(7 – x) = 3(x + 3)

GarryVolchara [31]

If you would like to solve 2 * (7 - x) = 3 * (x + 3), you can do this using the following steps:

2 * (7 - x) = 3 * (x + 3)
2 * 7 - 2 * x = 3 * x + 3 * 3
14 - 2 * x = 3 * x + 9
14 - 9 = 3 * x + 2 * x
5 = 5 * x
x = 1

The correct result would be x = 1.

50 pts, trigonometry

trasher [3.6K]

sin(0) = opposite/hypotenuse = 2/5

cos(0) = adjacent/hypotenuse = sqrt21/5

tan(0) = opposite/adjacent = 2/sqrt21 * sqrt21/sqrt21 = 2sqrt21/21

cot(0) = adjacent/opposite = sqrt21/2

sec(0) = hypotenuse/adjacent = 5sqrt21/21

PLEASE HELP!!! Given angle circled dash=208° and a right triangle inscribed within a circle of radius 5, what is the value of x

natta225 [31]

Answer:

-4.41

Step-by-step explanation:

208° is a 3rd-quadrant angle, so its x-coordinate will be negative. Your calculator can tell you that 5 times the cosine of this angle is -4.41, or you can refer to a diagram.
