X=21<span>°
</span>y=31.5<span>°
Explanation:
Since it is a whole circle (360</span>°) and there are 40 section (90<span>° each).
2 of the 90</span>° +(180°)<span>are clearly stated there so you do:
360</span>°-180°=180<span>°
</span>
1. On the side that have 2 'y's you do:
90°-(12+15)=63
Then 63/2=31.5<span>°
</span>Therefore y=31.5<span>°
</span>
2. On the side with 3 'x's you do:
90<span>°-(12+15)=63
Then 63/3=21</span><span>°
</span>Therefore x=21<span>°
To cross check you do:
90+90+15+12+21+21+21+15+12+31.5+31.5=360
I hope you find this helpful.</span>

Answer:
the answer is D
Step-by-step explanation:
because trapezoid only have one pair of parallel sides
Answer:
x = 4
Explanation:
Since segment DE is parallel to AC, we can use Thales theorem and write the following equation:

Then, we can solve for x if we cross multiply as:

Therefore, the value of x is 4.
