Okay, the formula for this would be

$a^{2}$ + $b^{2}$ = $c^{2}$

Lets start with 4.

$7^{2}$ + $25^{2}$ = $c^{2}$

Simplify.

49 + 625 = $c^{2}$

674 = c

c = $\sqrt{674}$

c = 25.96

Which is ≈ 26

Suppose cos(a)=.325

tatyana61 [14]

The value of tan a is 2.9098

Explanation:

The given value is $\cos (a)=0.325$

Now, we shall find the value of sin (a), using the identity,

$\sin ^2(a)+\cos^2(a)=1$

Substituting the value of cos (a), we get,

$\sin ^2(a)+(0.325)^2=1\\\sin ^2(a)+0.1056=1$

Subtracting both sides by 0.1056, we have,

$\sin ^2(a)=0.8944$

Taking square root on both sides, we get,

$sin a= 0.9457$

Now, we shall substitute the value of sin (a) and cos (a) to determine the value of tan (a) in the identity $tan (a) =\frac{sin(a)}{cos(a)}$

$tan (a) =\frac{0.9457}{0.325}\\tan (a) = 2.9098$

Thus, the value of tan (a) is 2.9098

If the mass of your roommate is 150 lbm, what is his or her weight (lbf)?

Sav [38]

Answer: <em>Weight(lbf) = 4830</em>

Step-by-step explanation:

Given :

Mass of the roommate = 150 lbm

Since we know that g = $32.2 feet/s^{2}$

Therefore, we can calculate his/her weight in lbf using the following formula:

Weight(lbf) = Mass × g

Weight(lbf) = 150 × 32.2

<em>Weight(lbf) = 4830</em>
