The answer is 80 degrees. As you can see, the triangle is an isosceles triangle and both sides of the triangle equal 14. If both of the sides are congruent then the opposite angles are also congruent as well. Which means the 50 degrees in the left angle is congruent to the right angle, 50. Since triangles add up to 180 degrees, the answer for x would be 80.

Hope this helped :)

A rectangular prism and a cylinder both have a height of 8 m, and their cross-sectional areas are equal at every level parallel

Svetllana [295]

Answer:

The volume of the prism is

$V=72\pi\ m^3$

Step-by-step explanation:

we know that

The volume of the prism is given by the formula

$V=LWh$ ----> equation A

The volume of the cylinder is given by the formula

$V=\pi r^{2}h$ ---> equation B

Remember that

If the height is the same and their cross-sectional areas are equal at every level parallel to their respective bases, then their volumes are equal

Find the volume of the cylinder

$V=\pi r^{2}h$

substitute the given values

$V=\pi (3)^{2}(8)$

$V=72\pi\ m^3$

therefore

The volume of the prism is

$V=72\pi\ m^3$

Nuka is weaving beaded strips. The double number line shows that they can weave 7 \,\text{cm}7cm7, start text, c, m, end text of

Thepotemich [5.8K]

Number lines are used to represent numbers and ratios using regular intervals

Nuka can weave 8.75 cm of strip in 5 minutes

<h3>How to determine the length of strip</h3>

Represent the ratio with:

Ratio = Length : Time

From the number line, they can weave 7cm of the strip in 4 minutes.

So, we have:

Ratio = 7cm : 4 minutes

Represent the length of strip made in 5 minutes with x.

So, we have:

x : 5 minutes = 7cm : 4 minutes

Remove the common units

x : 5 = 7cm : 4

Express as fraction

$\frac x5 = \frac{7cm}{4}$

Multiply both sides by 5

$x= \frac{7cm}{4} * 5$

Evaluate the quotient and the product

$x= 8.75$

Hence, Nuka can weave 8.75 cm of strip in 5 minutes

In ΔRST, s = 58 inches, ∠R=115° and ∠S=19°. Find the length of r, to the nearest 10th of an inch.

Lorico [155]

Answer:

365.9 Inches

Step-by-step explanation:

To find the value of Sin A can be found using the sine rule. the rule states that the ratio of the length facing an angle in a triangle to the sine of the angle is constant. As such,

a/Sin A = b/Sin B = c/Sin C

Where is a is the side facing angle A, b is the side facing angle B and c is the side facing angle C.

Hence,

58/Sin 19 = r/Sin 115

r = 58 Sin 115/ Sin 19

= 365.9 Inches
