we know that
the sum of an exterior angle and the adjacent interior angle.of a triangle is equal to 180 degrees, because are supplementary angles
therefore
the answer is the option
An exterior angle is supplementary to the adjacent interior angle.
The answer is b. x=y, if you need help as to why ill be glad to help
Answer:
B
Step-by-step explanation:
5(t - 1) = 5t - 5
B, 5t + (-5)
+ and - make -
5t - 5
A trapezoid is a quadrilateral that has two parallel sides with a height.
<h3>The proof for trapezoid</h3>
From the diagram, AK = 1/2(AD-BC)
The combination of the bases of the equilateral triangle and the parallelogram is = the base of the trapezoid.
Therefore, BC = AD - 2AK
Make AK the subject of formula,
AK= 1/2 (AD -BC)
- From the second equation given,
KD = 1/2(AD - BC). This is wrong because of the following,
BC is parallel to KD.
Therefore length of KD = BC - AK and not KD = 1/2(AD - BC).

.84(25)=21
84%=.84
So 84%of 24 is .84*25
