Answer:

see explanation

Step-by-step explanation:

Note that

sin60° = \frac{\sqrt{3} }{2}, cos60° = \frac{1}{2}

Using trig. ratios in the right triangle

sin60° = \frac{opp}{hyp} = \frac{x}{18} = \frac{\sqrt{3} }{2} ( cross- multiply )

2x = 18\sqrt{3} ( divide both sides by 2)

x = \frac{18\sqrt{3} }{2} = 9\sqrt{3}

-----------------------------------------------------------------------------

cos60° = \frac{adj}{hyp} = \frac{y}{18} = \frac{1}{2} ( cross- multiply )

2y = 18 ( divide both sides by 2 )

y = 9

forsale [732]
So a triangle has a total of 180 degrees
107 + 2x-5 +x = 180
solve for x
112 + 3x = 180
-112           -112
3x = 68
x = 22.6667 degrees

Write the equation of the line that passes. Throught the point (-2,1)and (0,8)put your aswer in fully reduce point slope form un
Soloha48 [4]

Answer:

Step-by-step explanation:

first, we need to find the slope

slope = (y2 - y1) / (x2 - x1)

(-2,1)...x1 = -2 and y1 = 1

(0,8)...x2 = 0 and y2 = 8

now sub

slope = (8 - 1) / (0- (-2) = 7/(0 + 2) = 7/2

point slope form : y - y1 = m(x - x1)

using point (-2,1)....x1 = -2 and y1 = 1

slope(m) = 7/2

now sub

y - 1 = 7/2(x - (-2) =

y - 1 = 7/2(x + 2) <==== here is one answer

y - y1 = m(x - x1)

using point (0,8)...x1 = 0 and y1 = 8

slope(m) = 7/2

now sub

y - 8 = 7/2(x - 0) <===== another possible answer
