Question

If m9 119, What is the sim of measures of 11 and 16

Answer 1

From the given figure

<9 and <11 are in the corresponding position, then

If line c is parallel to line d, then

`\angle9=\angle11`

Since <9 = 119 degrees, then

<11 = 119 degrees

Since <11 and <16 are vertically opposite angles, then

`\angle11=\angle16`

Since <11 = 119 degrees, then

<16 = 119 degrees

Add the measures of <11 and <16

`\angle11+\angle16=119+119=238^(\circ)`

The sum of the measures of <11 and <16 is 238 degrees

The answer is the 2nd choice
