Answer:

The answer is 16π ft²

Step-by-step explanation:

What he need to do is "act" like there is a triangle in the circle, so the radius is 4, 4*2=diameter, 8, thats the length of the triangle, the height of the triangle is 4, now we find the area of the triangle, 8*4=32, 32/2=16

This is for anyone who needs it in the future

A horizontal line has points J, K, L. A line extends from point K up and to the right to point M. Angle J K M is (10 y + 6) degr
Temka [501]

Answer:

The found values are:

y = 10

<JKM = 106°

<MKL = 74°

Step-by-step explanation:

(See the diagram attached)

As JKL is a straight horizontal line, angle measure from JK to KL is 180°.

We can see in the diagram that line KM is dividing this angle of 180° into 2 unequal parts.

Which means that the sum of <JKM and <MKL is equals to 180°.

Mathematically, it can be written as:

Substitute the values of both angle to solve the equation:

(10y+6)+(8y-6) = 180\\18y=180\\y=\frac{180}{18}\\y=10

Put in the formulas of both angle to find their values:

<JKM = 10y + 6

<JKM = 10(10)+6

<JKM = 106°

<MKL = 8y - 6

<MKL = 8(10)-6

<MKL = 74°
