Answer:

Step-by-step explanation:

Sin 21 = $\frac{opposite side}{hypotenuse}$

Sin 21 = $\frac{BC}{15}$

0.3583 = $\frac{BC}{15}$

0.3583*15 = BC

BC = 5.3745 = 5.37 m

Tan ∅ = $\frac{opposite side}{adjacent side}$

Tan ∅ = $\frac{4}{5.37}= 0.7448$

∅ = tan⁻¹ (0.7448) = 36.67 = 36.7

Solve this problem in your notebook using all four steps. A board 60 in. long is cut into two parts so that the longer piece is

Viktor [21]

X = shorter piece
y = longer piece = 5x

shorter piece + longer piece = 60
x + 5x = 60
6x = 60
x = 60/6
x = 10 in. <== shorter piece

y = 5x
y = 5(10)
y = 50 in. <== longer piece

Select the equations of the lines that are parallel to the line whose equation is y = 3x + 5. There might be more than one answe

o-na [289]

Parallel means they have the same slope.
The given equation has a slope of 3. Slope intercept equation: y = mx + b
a. 6x + 2y = 12
Subtract 6x from both sides.
2y = - 6x + 12
Divide both sides by 2.
y = -3x + 6 Not parallel

b. -3x + y = 8
Add 3x to both sides.
y = 3x + 8 Parallel

c. 3y = 9x
Divide both sides by 3
y = 3x Parallel

d. y = -1/3x Not parallel

B and C are parallel
