Do the Pythagorean theory to find the unknown side by doing:
c^2 = a^2 - b^2

Then you’ll have two sides and two angles.

Do sine law.

Sin(angle) / side (opposite to it) = Sin(angle) / side (opposite to it)

Find a:27=6:11, find a​
trasher [3.6K]

Answer:

a = 14.73

Step-by-step explanation:

This ratio can also be written like this:

\frac{a}{27} = \frac{6}{11}

Then you can cross multiply to get

11a = 6 x 27

11a = 162

Divide both sides by 11

11a / 11 = 162 / 11

a = 14.73

IrinaVladis [17]

Answer:

Step-by-step explanation:

f(\frac{7\pi}6)=2\sin(\frac{7\pi}6)=2\sin(\frac{7\pi}6)=2\sin(\pi+\frac{\pi}6)=-2\sin(\frac{\pi}6)=-2\cdot\frac12=-1
