Find the measures of each angle ( show work)

Part 11) , ,

Part 12) ,

Step-by-step explanation:

Part 11) we know that

Find the measure angle 3

The base angles of an isosceles trapezoid are equal in measure

so

Find the measure of angle 1

-----> by supplementary angles

Find the measure of angle 2

-----> by supplementary angles

Part 12) we know that

In a Kite the diagonals are perpendiculars

so

and

------> by complementary angles

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
