If the sine of an acute angle is 3/5, what is the cosine of<br> that angle?

Korvikt [17]

Answer:

The cosine of the angle is 4/5.

Step-by-step explanation:

An acute angle is between 0º and 90º, in the first quadrant of the trigonometric circle, in which both the sine and the cosine are positive values.

For each angle $\alpha$ , we have that:

$\sin^{2}{\alpha} + \cos^{2}{\alpha} = 1$

We have that:

$\sin{\alpha} = \frac{3}{5}$

$\sin^{2}{\alpha} + \cos^{2}{\alpha} = 1$

$(\frac{3}{5})^{2} + \cos^{2}{\alpha} = 1$

$\cos^{2}{\alpha} = \frac{16}{25}$

$\cos{\alpha} = \frac{4}{5}$

The cosine of the angle is 4/5.

In APQR, PQ- QR. If map

Hitman42 [59]

Answer:

3x-120 = x - 30

2x -120 = -30

2x= 90

x= 45

3(45) -120 (plug x into angle p to check your answer)

135-120

15 degrees

45-30 (plug x into angle r to make sure it's the same thing as angle p)

15 degrees (they're equal so now figure out angle Q and answer the question)

180 - (15 +15)

180- 30

150 is the measure of angle Q

so, the triangle is an obtuse isosceles triangle

Can someone help me please

Dafna1 [17]

Answer:

none

Explanation:

Fill in each option for x individually.

I) 9 $\leq$ -10 - 4(-1)

II) 9 $\leq$ -10 - 4(-3)

III) 9 $\leq$ -10 - 4(-2)

Then, simplify the right side of each inequality.

I) 9 $\leq$ -6

II) 9 $\leq$ 2

III) 9 $\leq$ -2

Each of these inequalities are flase. 9 is not less than or equal to any of these values, so the answer is none.
