Answer:

θ = 68°

Step-by-step explanation:

The side 3 is adjacent to the angle we need to find , and we know the hypothenuse so will use the cosθ function

cos θ = adj/ hyp = 3/8

To find the angle we need to apply the inverse function cos ^(-1) and use the calculator to solve it.

θ = cos ^(-1) (3/8) = 67.97

Round to the nearest degree and will have

θ = 68°

Answer:

68°

Step-by-step explanation:

The situation can be represented by a right triangle with the ladder as the hypotenuse and θ as the angle between the ladder and the ground.

Using the cosine ratio in the right triangle

cosθ = $\frac{adjacent}{hypotenuse}$ = $\frac{3}{8}$ , then

θ = $cos^{-1}$ ( $\frac{3}{8}$ ) ≈ 68° ( to the nearest degree )

Point C is the center of the circle. The measure of angle ACB is 3x + 120. Arc AB measures 65x – 4. Find the measure of arc AB.

katovenus [111]

In a circle The measurement of a CENTRAL ANGLE (vertex C) is equal to the measurement of the arc intercepted:

65x-4 = 3x+120 ===> 62x=124 & x= 2, hence the arc = 2

A TV that usually sells for $192.74 is on sale for 25% off. If sales tax on the TV is 5%, what is the price of the TV, including

Mashutka [201]

Answer:

Step-by-step explanation:

If you are saving 25%, you are still paying 75%, right? So the cost of the TV with a discount of 25% is 192.74(.75) which is $144.56

That's the cost of the TV on sale. Now we need to find the sales tax amount, if the sales tax is .05 as a decimal. We are paying $144.56 for the TV, which is 100% of the cost. On top of that, we are paying another 5%. So altogether, for the TV, we are paying 105% of the TV. Therefore,

144.56(1.05) = $151.79

How do i solve each proportion?

natali 33 [55]

You have to cross multiply (multiply the numerator of the first by the denominator of the second and the numerator of the second by the denominator of the first).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[19]

$\frac{x+4}{3} = \frac{4}{10}$

$10x+40=12$

$10x = -28$

$x=-2.8$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[21]

$\frac{4}{n+8} = \frac{10}{8}$

$32 = 8n + 64$

$8n = -32$

$n=-4$

Can someone find the length of the spine plss

morpeh [17]

Answer:

48.2 cm

Step-by-step explanation:

The bottom side of the large triangle has length 78 cm.

The bottom side of the right triangle has length 78 cm/2 = 39 cm.

Now we use the Pythagorean theorem to find the vertical side, the spine.

39² + s² = 62²

s² = 3844 - 1521

s² = 2323

s = 48.2

Answer: 48.2 cm
