Evaluate tan(cos^-1 3/5) and assume that all angles are in Quadrant I.
lorasvet [3.4K]

Answer:

Option c

Step-by-step explanation:

We assume that the angle is in the first quadrant.

Observe the attached image.

if u = cos ^{-1}(\frac{3}{5})

So:

cosu = \frac{3}{5}

By definition:

cosu= \frac{adjacent}{hypotenuse}

So:

adjacent side = 3

hypotenuse = 5.

Observe the attached image

We find the opposite side "x" using the Pythagorean theorem.

x=\sqrt{5^2 -3^2} \\x = 4

Then, for the angle u:

tanu = \frac{opposite}{adjacent}\\\\tanu = \frac{x}{3}\\\\tanu = \frac{4}{3}

Solve for a: 3a - 5(a - 2) = 34<br><br>A: a=1<br>b: a=-12<br>c: a=-22<br>d: a=0 ​
nalin [4]

Answer:

b. a=-12

Step-by-step explanation:

3a-5a+10=34

multiply -5 times a and -2

-2a+10=34

-5a from 3a

-2a=24

subtract 10 from both sides

a=-12

-2a divided by both sides
