Find sin θ if θ is in Quadrant III and tan θ = . 0.958

Leokris [45]

Use the following identities:
$sec^2 = 1 + tan^2 \\ \\ sec = \frac{1}{cos} \\ \\ sin^2 = 1 - cos^2$
Also because the angle is in quadrant 3, sin must be negative.
Therefore
$sin = - \sqrt{1 - \frac{1}{1 + tan^2}}$
Subbing in tan = 0.958
$sin \theta = -0.69178$

WILL BE MARKED AS BRAINLIEST !!! Solve (−22 −4 + 8)+ (52 + 2 − 25)

anygoal [31]

Answer:

Step-by-step explanation:

1) lets get rid of the parentheses, we dont really need them:

−22 −4 + 8+ 52 + 2 − 25

Following order of operations we need to work from left to right

-22-4=-26

-26+8=-18

-18+52=34
