How do I find the measure of the angle indicated with bold?

What is the length of BC in the right triangle below

Anna [14]

Answer:

<h2>15 units</h2>

The length of BC is 15 units.

Solution,

Hypotenuse(h)=?

perpendicular(p)=12

base(b)=9

Using Pythagoras theorem,

${h}^{2} = {p}^{2} + {b}^{2} \\ or \: {h}^{2} = {12}^{2} + {9}^{2} \\ or \: {h}^{2} = 12 \times 12 + 9 \times 9 \\ or \: {h}^{2} = 144 + 81 \\ or \: {h}^{2} = 225 \\ or \: h = \sqrt{225} \\ or \: h = \sqrt{ {15}^{2} } \\ h = 15$

hope this helps...

Good luck on your assignment....

Which of the following congruence statements are correct?

solong [7]

Only B and F are true. The letters are set up so the parts that you choose must have the letters in the same place on each triangle.

So if ABC is a triangle congruent to PQR
Then AB is congruent to PQ because AB are the first 2 letters of ABC and PQ are the first 2 letters of PQR.
AC is congruent to PR (why?)

Given:

Width of rectangular prism = 20 ft

height of rectangular prism = 12 ft

Length of rectangular prism = 45 ft

Cylindrical diameter = 20 ft

To find:

Volume of the tent

Solution:

Volume of the rectangular prism = length × width × height

= 45 × 20 × 12

Volume of the rectangular prism = 10800 ft³

Radius of cylinder = 20 ÷ 2 = 10 ft

Height of cylinder = length of rectangular prism

Volume of cylinder = $\pi r^{2} h$

Volume of half cylinder = $\frac{1}{2} \pi r^2h$

$$=\frac{1}{2} \times 3.142\times 10^2 \times45$

Volume of half cylinder = 7069.5 ft³

Volume of tent = volume of rectangular prism + volume of half cylinder

= 10800 ft³ + 7069.5 ft³

= 17869.5 ft³

= 17869 ft³ (nearest cubic foot)

The volume of the tent is 17869 cubic feet.
