Answer:
25) cos X = 12/37 cos X = 0.3243 X = 71.08 degrees
26) tan C = 32/24 tan C = 1.3333 C = 53.13 degrees
27) sin Z = 15/25 sin Z = 0.6 Z = 36.87 degrees
28) sin A = 32/40 sin A = 0.8 A = 53.13 degrees
29) sin Z = 40/50 sin Z = 0.8 Z = 53.13 degrees
The answers are below:
{X = 6, Y = -3}
Note: The first image is how to solve for Y. The second image is how to solve for X.
Answer:
Step-by-step explanation:
hello :
x²+ y² -12x - 18y +17 = 0 means : (x²-12x+36)-36+(y²-18y+81)-81-27 =0
(x-6)²+(y-9)² =12²....standard form when the center is (-6 , 9) and radius 12
Let

. You have

.
Taking the derivative, you get

The linear approximation to

near

is given by

So the value of

can be estimated as

15(x)+95= cost
15(77)+95=cost
1155+95=cost
