Answer:

.02mn - 0.12m -0.2

Step-by-step explanation:

.02m(n - 5) - .02(m + 10)

To get equivalent expression, remove the parenthesis

Distribute .02m inside the parenthesis

.02mn - 0.1- .02(m + 10)

Distribute -0.2 inside the parenthesis

.02mn - 0.1m- .02 m-0.2

Now combine like terms

.02mn - 0.12m -0.2

given sin A =3/-/34 and that angle S is in quadrant 1, find the exact value of tan A in simplest radical form using a ration
Vedmedyk [2.9K]

Answer:

\tan(A) = \frac{3}{5}

Step-by-step explanation:

Given

\sin(A) = \frac{3}{\sqrt {34}}

0 \le A \le 90 --- First Quadrant

Required

Find tan(A)

The sin of an angle is:

\tan(A) = \frac{Opposite}{Hypotenuse}

and

\sin(A) = \frac{3}{\sqrt {34}}

By comparison:

Opposite = 3

Hypotenuse = \sqrt{34

So, the Adjacent is:

Hypotenuse^2 = Adjacent^2 + Opposite^2

(\sqrt{34})^2 = Adjacent^2 + 3^2

34 = Adjacent^2 + 9

Collect like terms

Adjacent^2 =34 - 9

Adjacent^2 =25

Take square roots

Adjacent =\sqrt{25

Adjacent =5

The tangent of an angle is:

\tan(A) = \frac{Opposite}{Adjacent}

This gives:

\tan(A) = \frac{3}{5}

I need help please thank you hurry
Elena-2011 [213]

Answer:

Step-by-step explanation:

To get the other angles you need to do this

110+80+x+x=360

190+2x=360

2x=360-190

2x=170

X=170÷2

X=85
