Answer:

x ≈ 12.6 m

Step-by-step explanation:

By using cosine ratio in the given right triangle RTS,

cos(S)° = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

cos(33)° = \frac{\text{ST}}{\text{SR}}

cos(33)° = \frac{x}{15}

x = 15.cos(33)°

x = 12.58

x ≈ 12.6 m

Therefore, measure of side ST = 12.6 m is the answer.

Megan has $45.12 in her purse. She spends $7.89 for lunch and $21.25 for a pair of sunglasses.
tekilochka [14]

Answer:

Radda [10]
To find a volume of a cylinder we use the following formula:
v = \pi {r}^{2} h
Plug in the values:

v = \pi \times  {8}^{2}  \times 14
Take the square:
v = \pi \times 64 \times 14
Multiply the numbers:
v =896 \pi {m}^{2}

Can you please help me and explain this in a way that I can understand ​
melomori [17]

Answer:

180 Degrees

Step-by-step explanation:

So, m∠1 = m∠2 = m∠3 means that these angles are the same degrees

The question asks whats the degree of m∠CDG so first we find those points. In this image, it looks like points C,D and G form a line which is also equivalant to 180.

I hope you understand! If not, i'll try to elaborate more
