Find the third angle in a triangle when the other two angles are (2a-32)° and (3a+22)°

kati45 [8]

Answer:

(190-5a)°

Step-by-step explanation:

Sum of internal angles of a triangle equals to 180°

If the third angle is x, then we have:

(2a-32)°+(3a+22)° +x = 180°
(5a- 10)° +x= 180°
x= (180+10-5a)°
x= (190-5a)°

The third angle is: (190-5a)°

What is the volume, to the nearest whole cubic inch, of a cylinder with a height of 10 inches and a radius of 8 inches?

Stells [14]

Volume of a cylinder= pi x radius squared x height

3.14 x 8 squared x 10= 2009.6

= 2010 inches cubed

lmk if i’m wrong :)

Find the value of tan( π + θ) if θ terminates in Quadrant III and sinθ = -5/13

Vladimir79 [104]

ANSWER

$\tan(\pi + \theta)= \frac{5}{12}$

EXPLANATION

We first obtain

$\cos( \theta)$

using the Pythagorean Identity.

$\cos ^{2} ( \theta) + \sin ^{2} ( \theta) = 1$

$\implies \: \cos ^{2} ( \theta) + ( - \frac{5}{13} )^{2} = 1$

$\implies \: \cos ^{2} ( \theta) + \frac{25}{169}= 1$

$\implies \: \cos ^{2} ( \theta) = 1 - \frac{25}{169}$

$\implies \: \cos ^{2} ( \theta) = \frac{144}{169}$

$\implies \: \cos ( \theta) = \pm \: \sqrt{\frac{144}{169} }$

$\implies \: \cos ( \theta) = \pm \: \frac{12}{13}$

In the third quadrant, the cosine ratio is negative.

$\implies \: \cos ( \theta) = - \: \frac{12}{13}$

The tangent function has a period of π and $\pi + \theta$ is in the third quadrant.

This implies that:

$\tan(\pi + \theta)= \tan( \theta)$

$\tan(\pi + \theta)= \frac{ \sin( \theta) }{ \cos( \theta) }$

$\tan(\pi + \theta)= \frac{ - \frac{ 5}{13} }{ - \frac{12}{13} }$

This gives us:

$\tan(\pi + \theta)= \frac{5}{12}$
