Answer:
Step-by-step explanation:
<u><em>The question is</em></u>
Find the value of XY
see the attached figure to better understand the problem
we know that
-----> by segment addition postulate
If X is the midpoint WY
then
substitute in the formula above
substitute the given values and solve for XY
Subtract 6 both sides
Divide by 2 both sides
Rewrite
Answer:
1. 375
2. 294
Step-by-step explanation:
Area of a trapezoid
A = 1/2 (b1+b2) *h where b1 and b2 are the top and bottom of the trapezoide
1.
A = 1/2 (14+36) *15
= 1/2 (50)*15
= 25*15
375
A = 1/2 (21+7) *21
= 1/2 (28)*21
= 14*21
294
Answer:
122
Step-by-step explanation:
<HEB=180-(42+32)
=180-74
=106
<DEA=180-106 (straight line)
=74
<NAD=48+74(exterior angle = sum of 2 interior opposite angles)
<NAD=122
Answer: they both have four sides (quadrilateral)
