sin(73)=x/19

x= 18.169...

Answer is 18.2 feet

So if we have a right triangle with a 19ft hypotenuse or ladder, and it makes a 73deg angle with the ground. So we can use the sine of the angle to find the height.

sin(73)=y/19
y=19sin(73)
y=18.2ft is the height

Hope this helps. Any questions please just ask. Thank you.

Which equation could have been used to create this table?
Lyrx [107]

Answer:

y = 3x

Step-by-step explanation:

(1,3) (2,6)

The first step is to find the rate of change ( or slope)

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

m = (6-3)/(2-1)

m = 3/1

m = 3

Then  we need to use the point slope form of the equation of a line

y-y1 = m(x-x1)

y-3 = 3(x-1)

Distribute the 3

y-3 = 3x-3

Add 3 to each side

y-3+3 = 3x-3+3

y = 3x

The length of a rectangular wall is 16.5 feet. The height of the wall is 8.625 feet. Cameron determines the area of the wall to
iris [78.8K]

Answer:

<h2>Cameron solution is not reasonable, because it must have 4 decimals points, not three.</h2>

Step-by-step explanation:

When calculating the area of the rectangular wall, we have to multiply 16.5ft(8.625ft), if we observe, we have 4 decimals in total. The multiplications results 142.3125. So, Cameron solution is not reasonable, because he only included three decimals points, instead of four.

16.5ft(8.625ft)=142.3125ft^{2}

(d) If mZABD=60°, and point C is in the interior of ABD, then mZABC=40° and m/CBD=20°. Counterexample: m ZABC = [], m2 CBD = "
DENIUS [597]

The counter example: m∠ ABC = 35°, and m∠ CBD = 25°.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. When two planes intersect each other will create an angle.

Point C is the interior of ABD.

The measure of angle ABD is 60°.

The measure of angle ABC is 40°.

The measure of angle CBD is 20°.

Now when we add the angle ABC and CBD:

∠ ABC + ∠ CBD = 40° + 20°

∠ ABC + ∠ CBD = 60°

∠ ABC + ∠ CBD = ∠ ABD

The counter-example will be:

∠ ABD = ∠ ABC + ∠ CBD

60° = 35° + 25°

Therefore,

∠ ABC = 35° and ∠ CBD = 25°
