Sunny_sXe [5.5K]3 years ago
8 0

Answer:

x = 8, y = 4

Step-by-step explanation:

To find x use the sine ratio in the right triangle and the exact value

sin60° = \frac{\sqrt{3} }{2} , thus

sin60° = \frac{opposite}{hypotenuse} = \frac{4\sqrt{3} }{x} = \frac{\sqrt{3} }{2} ( cross- multiply )

x × \sqrt{3} = 8\sqrt{3} ( divide both sides by \sqrt{3} )

x = 8

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

To find y use the tangent ratio in the right triangle and the exact value

tan60° = \sqrt{3} , thus

tan60° = \frac{opposite}{adjacent} = \frac{4\sqrt{3} }{y} = \sqrt{3} ( multiply both sides by y )

4\sqrt{3} = y × \sqrt{3} ( divide both sides by \sqrt{3} )

y = 4

Write the equation of a line that is perpendicular to y=-0.3x. +6 and that passes through the point (3,-8)
nataly862011 [7]

Answer:

y=\frac{x}{0.3}-18 \ or \ 3y=10x-54

is the equation of perpendicular line.

Step-by-step explanation:

We are given , the equation of a line is  y=-0.3x. +6

We can deduce that the slope of the given line is m=-0.3

The slope of its perpendicular line would be , m_p= \frac{-1}{m} =\frac{1}{0.3}

Now using the point slope form, y-y1= m_p(x-x1)

Use the given point (3,-8) \ as\ (x1,y1) substituing these.

y-(-8)= \frac{1}{0.3} (x-3)\\y+8=\frac{x}{0.3} -10\\y=\frac{x}{0.3} -18

Therefore the required equation of a line that is perpendicular to y=-0.3x. +6 and that passes through the point (3,-8) is y=\frac{x}{0.3} -18[/tex]

Ganezh [65]

Answer:

55 mph

Step-by-step explanation:

First hour: 40 mph

Second, Third, Fourth hours:

180 miles / 3 hours = 60 mph

Average: 40 (hour 1) + 60 (hour 2) + 60 (hour 3) + 60 (hour 4) = 220 / 4 hours = 55 mph average

I hope this helps!

What is the answer to JML?
qaws [65]

Answer:

JML=126 (x=42)

Step-by-step explanation:

Since the whole angle is equal to 180, you take that and subtract it by the part of that angle you know. The remainder is JML. If you want to find x, you set 3x equal to 126.

See work attached for more.
