Step-by-step explanation:
Answer:
b=-11
Step-by-step explanation:
I assume you are looking to solve for the value of b.
<u>3(b+2)</u> x <u>2</u>= <u>4b-10</u>
2 2 4
<u>6(b+2)</u> = <u>4b-10</u>
4 4
x 4 x4
6(b+2) = 4b-10
6b+12=4b-10
-4b -4b
2b+12=-10
-12 -12
<u>2b</u>=<u>-22</u>
2 2
b=-11
M = 3/4
Remeber y = mx + c
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°.
