Find the value of x. Then find the measure of the two interior angles. x =

∡A =
º

∡B =
º

Here

A exterior angle is equal to two interior angles

Now

5y+3°+4y+8°=146°

or, 9y=146-11

or, y=135/9

or, y=15°

Again

AngleA=5y+3°

=5*15°+3°

=78°

AngleB=4y+8°

=4*15°+8°

=68°

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
