Find the value of the missing variables.

Answer:

$x^{\circ}=35^{\circ}\\ \\y^{\circ}=55^{\circ}$

Step-by-step explanation:

The measure of arc which the right triange cuts from the circle is $70^{\circ},$ this means the central angle has the same measure.

Angle with measure $x^{\circ}$ is inscribed angle subtended on the given arc. Its measure is half the measure of the central angle, hence

$x^{\circ}=\dfrac{1}{2}\cdot 70^{\circ}=35^{\circ}$

Angles with measures $x^{\circ}$ and $y^{\circ}$ are complementary angles (add up to 90°), so

$y^{\circ}=90^{\circ}-35^{\circ}=55^{\circ}$

Which of the following could be used to calculate the area of a sector in the circle shown below

lara [203]

Answer:

Therefore the Last option is correct

$\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})$

Step-by-step explanation:

Given:

Radius = r = 8 in

θ = 42°

To Find:

Area of Sector = ?

Solution:

We know that

$\textrm{Area of Sector}=\pi (Radius)^{2}\times \frac{\theta}{360}$

Substituting the given values in the formula we get

$\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})$

Which is the required Answer.

Therefore the Last option is correct

$\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})$

A jet ski rental charges A flat rate of $75 ,plus an additional $60 per hour you want to spend less than $200. for how many hour

cluponka [151]

The equation to solve would be setting

60×- the m plus 75,the b set to 200 the maximum that's wanted to be used. the equation will look like this

200=60x+75

-75. -75

125=60x
125/60 60x/60

2.08=x

and since you cant round the time the answer will be left at 2
