Answer:

90 Degrees

Step-by-step explanation:

This is a very cool theorem. When the longest side of a triangle is the diameter of the circle, which in the picture you can see it is, the angle opposite to it is ALWAYS 90 degrees. Remember that the points have to be on the circle for this theoroem to work. I forget what the theoroems is called, but it is very helpful.

Thanks and have a great day!

Divide $414 into three parts such that first one is two-third of the second and the ratio between second and third is 5 : 7.

Marta_Voda [28]

Answer:

$90, $135, $189

Step-by-step explanation:

Since the first part of the ratio is two- thirds of the second, then

first part = $\frac{2}{3}$ × 5 = $\frac{10}{3}$

The ratio is then

$\frac{10}{3}$ : 5 : 7

Sum the 3 parts of the ratio

$\frac{10}{3}$ + 5 + 7 = $\frac{46}{3}$

Divide the amount to be shared by the sum to find the value of one part of the ratio.

$414 × $\frac{3}{46}$ = $27 ← value of 1 part of the ratio, then

$\frac{10}{3}$ × $27 = $90

5 × $27 = $135

7 × $27 = $189

The 3 parts are $90, $135, $189

The circumference of a circle 25.12ft. What is the circle’s diameter (take =3.14

marshall27 [118]

Answer:

Diameter = 8 ft

Step-by-step explanation:

To find diameter, we need to work backwards from the formula for circumference of a circle.

Circumference = 2πr

given that π = 3.14

Circumference = 2*3.14*r

25.12 = 2*3.14*r

25.12 = 6.28 * r

4 = r

Radius = 4

Formula for Diameter =

D = 2r

D = 2*4

D = 8

Diameter = 8

Lets Check

Circumference = 2 * 3.14 * 4

Circumference = 25.12

Correct

If my answer is incorrect, pls correct me!
