Answer:
They are: area of sector and area of triangle
Step-by-step explanation:
Area of segment=area of sector - area of triangle
So we need both the area of sector and area of triangle to calculate for the area of a segment
Answer:
Option "D" is correct.
Step-by-step explanation:

To eliminate negatives
They are interchanged thus it gives us option D.
Separate the variables:

Separate the left side into partial fractions. We want coefficients a and b such that





So we have

Integrating both sides yields






With the initial condition y(0) = 1, we find

so that the particular solution is

It's not too hard to solve explicitly for y; notice that

Then






Answer:
z = 23 degrees
Step-by-step explanation:
Total degree inside a triangle = 180
We can add up the 2 angles we got.
62 + 95 = 157
Subtract 157 from 180.
180 - 157 = 23
Check = the angle missing is an acute angle (less than 90 degrees) and 23 is less than 90 degrees so it is possible.
I hope this helped and please mark me as brainliest!
