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
