RoseWind [281]

Answer:

m(arc AC) = 72°

m(arc BD) = 108°

m∠DEB = 90°

Step-by-step explanation:

Ratio of the measure of arc AC, arc BC, arc BD and arc AD = 4 : 2 : 6 : 8

Since, m(arc AC) + m(arc CB) + m(arc BD) + m(arc AD) = 360°

By the property of ratio,

Measure of arc AC = $\frac{4}{4+2+6+8}\times (360^0)$

= $\frac{4\times 360}{20}$

= 72°

Measure of arc BD = $\frac{6}{4+2+6+8}\times (360^0)$

= $\frac{6\times 360}{20}$

= 108°

Measure of ∠DEB = $\frac{1}{2}m(arcAC + arc BD)$

= $\frac{1}{2}(72+108)$

= 90°

-4=x/20-5 Solve for x

garik1379 [7]

Answer:

x = 20

Step-by-step explanation:

I'm no mathematician but...

- 4 = x / 20 - 5

If you move the five to the other side using addition you get:

1 = x / 20

Then multiply 20 on both sides

20 = x

Answer:

x< 10

Step-by-step explanation:

To start the absolute difference between 20 and 5 is 15. Next, write out an equation for the problem:

x * 1.5 < 15,

Then divide by 1.5 on both sides...

Boom! x < 10.
