Answer:
x = 25.7
Step-by-step explanation:
We know the adjacent side to the angle and the hypotenuse on a right triangle
cos theta = adj / hyp
cos 18 = x/27
27 cos 18 =x
25.67852594=x
Rounding to the nearest tenth
x = 25.7
Answer:
I. 5
Step-by-step explanation:
- 140° and 8x° are on the straight angle and they are both equal 180°
to find the value of x:
140 + 8x = 180
8x = 180 - 140
8x = 40
x = 40/8
x = 5
Answer:
x = 4/5
Step-by-step explanation:
1) Group like terms
4x + 7x + 5x - 2 - 10 = x
2) Add similar elements
16x - 2 - 10 = x
3) Subtract
16x - 12 = x
4) Add 12 to both sides
16x - 12 + 12 = x + 12
5) Simplify
16x = x + 12
6) Subtract x from both sides
16x - x = x + 12 - x
7) Simplify
15x = 12
8) Divide both sides by 15
15x/15 = 12/15
9) Simplify
x = 4/5
Step-by-step explanation:
9 x 4=36 is the answer

<u>Given</u>
- a = m(2) + 2
- value of a when m = -3
<u>Substitute m with -3</u>
a = -3*2 + 2
a = -6 + 2
a = -4
<u>Answer</u>
The value of a when m = -3 is -4
