Answer:
1.5
Step-by-step explanation:
Ok so cos(x) = sin(90-x) so using that you can get sin(7x-15) = sin(90-(3x+5)) so 7x-15 = -3x+85. 10x = 100 and x = 10. Use that to find the 2 angles are 55 and 35
We can find the diameter by dividing the circumference by 3.14
d = 22
Thus, our radius is 11.
r = 11
Now, let's use the area formula (

) to solve for the area.
a =
Answer:
The standard equation for an ellipse, x 2 / a 2 + y2 / b 2 = 1
Step-by-step explanation:
it represents an ellipse centered at the origin and with axes lying along the coordinate axes.
5 x 4= 20
8 x 2 = 16
36 + 2 + 2 = 40
40 square inches
