An isosceles triangle △ABC with the base BC is inscribed in a circle. Find the measures of angles of the triangle, if measure of

____ [38]

Answer:

angle at A: 51°
base angles: 64.5°

Step-by-step explanation:

The measure of the inscribed angle BAC is half the measure of the intercepted arc BC, so is 102°/2 = 51°.

The base angles at B and C are the complement of half this value, or ...

90° -(51°/2) = 64.5°

The angle measures in the triangle are ...

∠A = 51°

∠B = ∠C = 64.5°

A rectangular piece of paper is 44 cm long and 20 cm wide. A cylinder is forms by rolling the paper along its length. Find its v

Musya8 [376]

Answer:

3081.24 cm³ (nearest hundredth)

Step-by-step explanation:

<u>Formulas</u>

$\textsf{Circumference of a circle}=\sf 2 \pi r\quad\textsf{(where r is the radius)}$

$\textsf{Volume of a cylinder}=\sf \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}$

If a rectangular piece of paper is rolled along its length to form a cylinder:

circumference = 44 cm
height = 20 cm

To calculate the volume of the formed cylinder, determine the radius by using the circumference formula:

$\implies \sf 2 \pi r = 44$

$\implies \sf r = \dfrac{44}{2 \pi}$

$\implies \sf r =\dfrac{22}{\pi}$

Substitute the round radius into the formula for Volume and solve for V:

$\implies \sf V=\pi \left(\dfrac{22}{\pi}\right)^2(20)$

$\implies \sf V=\pi \left(\dfrac{484}{\pi^2}\right)(20)$

$\implies \sf V=\left(\dfrac{484}{\pi}\right)(20)$

$\implies \sf V=\dfrac{9680}{\pi}$

$\implies \sf V=3081.239698...cm^3$

Therefore, the volume of the cylinder is 3081.24 cm³ (nearest hundredth).

The diameters of bolts produced in a machine shop are normally distributed with a mean of 6.46 millimeters and a standard deviat

Varvara68 [4.7K]

Answer:

Step-by-step explanation:

Let X be the diameter of bolts produced in a machine shop

X is normal with mean = 6.46 mm and std dev = 0.05 mm.

We are to find the two diameters that separate the top 9% and the bottom 9%.

We can use std normal distribution value for this and from Z we can calculate X values

P(Z<z) = 0.09 and P(Z<z1) = 0.91

z=-1.341 and z1 = +1.341

Corresponding X values would be

for bottom 9%

X = 6.46-1.341*0.05 = 6.39295

X = 6.46+1.341*0.05=6.52305

What is the diameter of the inscribed circle of the triangle?

Fofino [41]

The value of diameter for the given triangle inscribed in a circle will be 22.

<h3>What is a circle?</h3>

A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.

In our daily life, we always see circular objects for example our bike wheel.

The longest line which can be drawn inside the circle will be the diameter.

As per the given triangle inscribed a circle.

The length x +2 and 2x - 7 will be the radius of the circle and the sides of the triangle will be the tangent of the circle.

x + 2 = 2x - 7

2 = 2x - x - 7

x = 9

Thus, radius = 9 + 2 = 11

Diameter = 11 x 2 = 22 units.

Hence "The value of diameter for the given triangle inscribed in a circle will be 22".
