Please help me!!!!! How do you get 67.3 and 112.7 from .9228
antoniya [11.8K]

Answer and Step-by-step explanation:

You are correct in that we need to use the Law of Sines: \frac{c}{sinC} =\frac{b}{sinB}=\frac{a}{sinA}.

Here, when we use the Law of Sines, we have: \frac{28}{sin(63)}=\frac{29}{sinB}.

Cross multiply:

(sinB) * 28 = (sin63) * 29

28sinB ≈ 25.839

sinB ≈ 0.9228

Now, in order to solve for B, we need to use inverse sin (sin^{-1}):

sin^{-1}(sinB)=sin^{-1}(0.9228)

The sines on the left cancel out, and we're left with:

B ≈ 67.3 degrees

Now, one thing to keep in mind when doing Law of Sines is that there is potentially more than one answer possible for the degree measure. The other degree measure can be found by subtracting this one from 180:

180 - 67.3 = 112.7 degrees.

Hope this helps!

A golfer wants to determine if the type of driver she uses each year can be used to predict the amount of improvement in her gam
Black_prince [1.1K]

Answer:

The type of driver

Step-by-step explanation:

The term known as '' response variable'' is use in describing a variable that changes when you alter an examination or a test. Just like its name implies, it is the ''response'' that one gets when the other variable that is the Explanatory Variable are being altered.

In this question, the golfer will have to be changing the type of drivers that she is using in order to be able to know whether these changes in drivers will increase her game performance. Hence, the Explanatory Variable is the type of driver in which the golfer changes which is being use to define the performance of the golfer.

Hello <span>Vmcdowell43

The word Thanks is a shorter way of saying Thank you. Many people use it because it is easier.

The word yes is a simple way to agree with something.

Hope that helps!

How much bigger is 3/8 than 1/3 answer as a fraction
alekssr [168]
You would first need to find a common denominator for 3/8 and 1/3 the common denominator would be 24 because 8 times three is 24 and 3 times 8 is 24. After you find your common denominator your fraction becomes 9/24 + 8/24. This gives you 17/24.
