The acute angles of a right triangle are complementary, so $\boxed{m\angle F=34^{\circ}}$ .

Using right-angle trigonometry, we know that

$\cos 56^{\circ}=\frac{26}{DF}\\\\DF=\frac{26}{\cos 56^{\circ}}\\\\\boxed{DF \approx 46.5}$

$\tan 56^{\circ}=\frac{FE}{26}\\\\FE=26 \tan 56^{\circ}\\\\\boxed{FE \approx 38.5}$

Answer:

$\frac{-5}{28}$

Step-by-step explanation:

Given:

$\frac{-1}{5} * (\frac{3}{4} + \frac{1}{7})$

Required:

Solve

Solution:

$\frac{-1}{5} * (\frac{3}{4} + \frac{1}{7})$

Apply distributive property by multiplying each reaction in the box by -⅕

$(\frac{-1}{5} * \frac{3}{4}) + (\frac{-1}{5} * \frac{1}{7})$

$\frac{-3}{20} + \frac{-1}{35}$

Add together. Common denominator is 140. Therefore:

$\frac{-21 + (-4)}{140}$

$\frac{-25}{140}$

Simplify further

$\frac{-5}{28}$

What is the length of the cylinder's height? Please help

raketka [301]

Answer:

Height = 9 cm which means Option C is the answer

Step-by-step explanation:

In the question we are given ,

Volume of cylinder = 225π cm³

Radius of cylinder = 5 cm

And , we have to find the height of cylinder .

We know that ,

$\longrightarrow \pink{ \boxed{Volume \: of \: Cylinder = \pi r {}^{2}h }} \longleftarrow$

Our solution starts from here :

$\longmapsto \: \pi \: r {}^{2} h = 225\pi$

Step 1 : Cancelling π with π :

$\longmapsto \: \cancel{\pi} \: r {}^{2} h = 225 \cancel{\pi}$

Step 2 : Substituting value of radius which is 5 cm in the formula :

$\longmapsto \: (5) {}^{2} \times h = 225$

$\longmapsto \: 25h = 225$

Step 3 : Transposing 25 to right hand side :

$\longmapsto \: h = \frac{225}{25}$

Step 4 : Cancelling 225 by 25 :

$\longmapsto \: \red{\boxed{h = 9 \: cm}}$

Henceforth , height of cylinder is 9 cm
