Answer:
12
Step-by-step explanation:
- Hypotenuse= ML
- Perpendicular=KL=15
- Base= KM=8
By using Pythagoras theorem.
- h²=p²+b²
- ML²=15²+8²
- ML²=225+64
- ML=√289
Therefore ML= 17...

1 yard = 36 inches
So,
39 inches times the number of yards
39inches times (x)yards
39(x)

How about we argue if you give me brainliest or not?
Looks more like Trig than Algebra II
They want us to apply the sum angle formula to 
5π/6 is 150°; I find it easier to think in degrees.
When the tangent of x is 3/4 that's a right triangle with opposite 3, adjacent 4 so hypotenuse 5. So a sine of 3/5 and a cosine of 4/5, both positive because we're told x is in the first quadrant.
The sine sum angle formula is


We know sin 150° = sin 30° = 1/2 and cos 150° = - cos 30° = -√3/2
