Two students use different methods to solve this multiplication problem: 12⋅−445 Read each of their methods below and then enter numbers to correctly complete their work. CLEAR CHECK Barbara writes each number as a fraction and then multiplies. 1 4 1 4 • −4 = • = 2 5 2 9 Christopher writes the mixed number as a sum and uses the distributive property. 1 4 1 4 1 1 • −4 = ( −4 + − ) = • + • = + 2 5 2 5 2 2 Barbara's and Christopher's answers will be equal. Write the answer as a mixed number in simplest form.

we know that

1) the inscribed angle measures half of the arc it comprises.

so

m∠dgf= > expression

2) the opposite angles in an inscribed quadrilateral are supplementary angles

so

m∠dgf=

m∠dgf=°

substitute in the expression to find the value of arc ef

therefore

the answer is

the measure of the arc ef is
