Answer:
<h2>
140°</h2>
solution,
Let <DEF= x°
<CDE= 2x°
<BAF= 90°
The sum of interior angle of hexagon= 720°
<A + <B + <C + <D + <E +<F = 720°

Again,

Hope this helps...
Good luck on your assignment..
Answer:
Step-by-step explanation:
Answer "A"
Dodecahedron
-7(x+y=525)-7
3x+7y=2775
-7x-7y=-3675
3x+7y=2775
-4x=-900
X=-900/-4
X=225
Answer is c
Answer:
C, 38°
Step-by-step explanation:
ray UW is the angle bisector of ∠VUT
--> m∠VUW = m∠WUT = 1/2 m∠VUT
<=> 4x + 6 = 6x - 10
<=> 6 + 10 = 6x - 4x
<=> 2x = 16
<=> x = 8
So, the measure of m∠WUT is: 6x - 10 = 6 . 8 - 10 = 48 - 10 = 38°
