Answer:
m∠DAB is 114°
Step-by-step explanation:
The given parameters are;
The dimensions of the given parallelogram ABCD are AD = 19, EC = 15, m∠ABC = 66°, m∠DAC = 78°, m∠BDC = 19°
Given that in parallelogram ABCD, the same side interior angles are supplementary, we have;
m∠ABC and m∠DAB are supplementary
Therefore;
m∠ABC + m∠DAB = 180° by definition of supplementary angles
66° + m∠DAB = 180°
m∠DAB = 180° - 66° = 114°
m∠DAB = 114°.
Answer:
H
Step-by-step explanation:
Let a represent Ann's height, and let j represent Jay's height
Break up the sentence into the key parts.
"The difference between Ann's and Jay's heights" "is" "half of Jay's height"
"The difference between Ann's and Jay's heights" becomes the expression:
a - j
"is" is math means an equal sign '='
"half of Jay's height" becomes the expression: (1/2)j
Put the 3 parts together and get the equation:
a - j = (1/2)j,
Since all the equations in the answer choices are in terms of a, solve the above equation for a...
a = (1/2)j + j, which is answer H
First you can subtract 6h-8h =-2h
4-2h=60
-4-2h=-4
------------
2h=56
Now divide and you get 56/2 =28
