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.

Suppose that P is the point on the unit circle obtained by rotating the initial ray counterclockwise through 330 degrees. Find t
Flauer [41]

Answer:

Reference angle will be 30°

sin(330°) will be equal to \frac{-1}{2}

cos(330°) will be equal to 0.866

Step-by-step explanation:

We have given angle is 330°

As the angle 330^{\circ} is in forth quadrant

We know that in forth quadrant the reference angle is given by

Reference angle =360-angle

As the angle is 330°

So the reference angle will be =360-330=30^{\circ}

Now we have to find the value of

sin(330°) =sin(2\pi -30)=-sin(30)=\frac{-1}{2}

And now cos(330^{\circ})=cos(2\pi -30)=cos30=0.866

In the figure below what is the value of x?
vazorg [7]

Answer:

The value of x is 106

Step-by-step explanation:

Let us solve the question

In the given figure

∵ The triangle in the given figure has two sides equal

→ That means the triangle is an isosceles triangle

∴ The triangle is isosceles

∵ In the isosceles triangle, the base angles are equal in measures

∵ The measure of one base angle is 37°

∴ The measure of other base angle is 37°

→ The sum of the measures of the interior angles of a Δ is 180°

∵ 37° + 37° + x = 180°

→ Add the like terms

∴ 74° + x = 180°

→ Subtract 74 from both sides

∵ 74 - 74 + x = 180 - 74

∴ x = 106

∴ The value of x is 106

The cost of 1 m ribbon is ₹ 75. Find the cost of 7/5 metres of ribbon​
Margaret [11]

Given that

The cost of 1 m ribbon = Rs.75

The cost of 7/5 m ribbon

→ (7/5)×75

→ (7×75)/5

→7×15

→₹ 105

The cost of 7/5 m ribbon is ₹105.
