70 given: e, f, q, d∈k(o),o ∈ ed, m∠dfq = 10°, measure of arc ef = 28° find: angles of △efq

The measures of angles of triangle EFQ are

1)

2)

3)

Step-by-step explanation:

step 1

Find the measure of arc QD

we know that

The inscribed angle is half that of the arc it comprises.

substitute the given value

step 2

Find the measure of arc FQ

we know that

---> because ED is a diameter (the diameter divide the circle into two equal parts)

substitute the given values

step 3

Find the measure of angle EFQ

we know that

The inscribed angle is half that of the arc it comprises.

substitute the given value

step 4

Find the measure of angle FEQ

we know that

The inscribed angle is half that of the arc it comprises.

substitute the given value

step 5

Find the measure of angle EQF

we know that

The inscribed angle is half that of the arc it comprises.

substitute the given value

i think 1: 2
