Answer:
-9?
Step-by-step explanation:
We have to relate the angles of the trapezoid in order to find the measure of BAD.
Given:
Then
The angles are congruent because if AD and BC are congruent, and the lines are parallel, they sides will form the same angles.
Also, as the segment AD is "cut" by two parallel lines, the angles BAD and ADC are consecutive interior angles and are, therefore, supplementary.
Then, we can write:
Now, with the value of x, we can calculate the measure of BAD as:
Answer: the measure of BAD is 74°.
Answer:
6.2
Step-by-step explanation:
Jack was planting a tree. He was to dig a hole that was 3 feet deep for every 5 feet of tree height. How deep should he dig the hole for a tree that is 17feet high.
Calculations Cross multiplication
=
5x = 2 x 13
Divide by 5 to isolate x
=
x = 10.2
Answer = 10.2
