According to law of cosines the length of RQ can be written as .
Given the length PR is 6 , the length of RQ is p, the length of PQ is 8 and the angle RPQ is 39 degrees.
A length of the triangle can be written as according to law of cosines if sides are given and one angle is
We have to just put the values in the above equation.
as .
p is the side opposite to angle given , the length of other sides are 6 and 8 and angle is 39 degrees.
Hence the side can be written as according to law of cosines if the angle is 39 degrees is as .

Let F the fraction that we want:
Answer:
Step-by-step explanation:
Product of 5 and a number: 5n
Six more than that would be 5n + 6
Finally, "six more than the product of 5 and a number, decreased by one" would be
5n + 6 - 1, or 5n + 5
Answer:
168 square inches
Step-by-step explanation:
Assuming these are the dimensions of a rectangular prism, then the surface area is given by
TSA=2(lw+lh+wh)
We substitute the dimensions into the formula to obtain:
TSA=2(2*9+2*6+9*6)
We simplify to get:
TSA=2(18+12+54)
TSA=2(84)
TSA=168 square inches
Answer:
The answer is 4 r 1.
Step-by-step explanation:
We kbow that 9 time 4 will get us 36, so that's what we put in the two boxes below the 37. Then, we subtract 36 from 37 and get 1. The one will go in the box below the 36. This means our answer will be 4 r 1. Hope this helps :)
