Answer:

57.8 degrees

Step-by-step explanation:

You can find this using inverse tangent, which is opposite over adjacent. You plug inverse tan of 35/22 into a calculator and that's what you get.

A student determined that the area of the segment of c shown above is Asegment = 137.71 ft2. The student's work is shown below.

ivolga24 [154]

Answer:

Option D. The student did not use the correct formula to calculate the area of the segment

Step-by-step explanation:

step 1

Find the area of the isosceles triangle

Applying the law of sines

$A=\frac{1}{2}(12^{2})sin(60\°)=62.35\ ft^{2}$

step 2

Find the area of the sector

The area of the sector is 1/6 of the area of the circle

$A=\pi r^{2}/6$

substitute the value

$A=(3.14)(12)^{2}/6=75.36\ ft^{2}$

step 3

Find the area of the segment

The area of the segment is equal to the area of sector minus the area of triangle

$A=75.36\ ft^{2}-62.35\ ft^{2}=13.01\ ft^{2}$

therefore

The student did not use the correct formula to calculate the area of the segment

salini's mother's present age is 8 times salini's present age five years from now salini's age will be 1/4th of of his mother's

choli [55]

Answer:

salini -= 5 years

mother = 40years

Step-by-step explanation:

$salini = x \\ mother =8x \\ x + 5 = 1 \: of \: 8x \\ x + 5 = 2x \\ 5 = x$

$5 = x$

then you equate the values of x
