Solve ( 2 4/16 + 3 2/3 )
elena-s [515]

Answer:

5 11/12

Step-by-step explanation:

2 4/16 = 2 1/4

2 1/4 + 3 2/3 = 9/4 + 11/3

27/12 + 44/12 = 71/12 = 5 11/12

Could someone help i’ll mark brainliest! please explain too
-BARSIC- [3]

Answer:

C. 8

Step-by-step explanation:

I almost thought this was going to be Pythagorean Theorem, but no.

Use Cosine Law:

cos θ =  \frac{10^2 + 21^2 - 17^2}{2(10)(21)}

θ = cos−1(0.6)

θ = 53.130...

Now use the SOHCAHTOA ratio for sine (\frac{opposite}{hypotenuse}) to find x now that you have one angle:

sin θ = \frac{x}{10}

x = 10sinθ (θ isn't needed to be written out as it is shown in the equation above)

x = 8
