Answer:
Step-by-step explanation:
D=106
E=54
F=20
D is an AEA im pretty sure meaning itʻll be equal to 106
E Is a vertical angle to 54
and for F everything will equal to 180 so 180-106-54=20
I hope this helps have a good day!

Step-by-step explanation:
Answer:
70 degrees, 21 degrees, 37 degrees
Step-by-step explanation:
For the rectangle
- Angle B= 90 degrees<em> (right angle)</em>
Find Angle AED = 180-46-90=44 degrees
All angles add up to 180 so we can find x
66+44=110, therefore Angle x = 180-110=70 degrees
XYZ is equilateral therefore all angles = 60 degrees
This allows us to find angle WZX, 180-60=120
Angle X=180-120-39=21 degrees
PQR is isoceles so the base angels are equal QRP=71 degrees
180-71=109 degrees. 180-109-34=37 degrees = Angle X
Good Luck!!
Hi there!
In order to figure out the total measures of interior angles of a polygon, you can use this equation: (n-2) * 180.
#1 - First, let's figure out the total measure of interior angles
WORK:
(6 - 2) * 180 = 720
Next, we can add up all of the values and set it equal to the total interior angle measures. Since the two unknown angles are congruent, we can show those as 2x.
WORK:
90 + 149 + 103 + 108 + 2x = 720
2x + 441 = 720
2x = 279
x = 139.5 degrees
#2 - In any polygon, the value of the exterior angles always adds up to 360. Using that, we can create another equation, adding up the values and setting it equal to 360. For the one interior angle that is there, we need to find it's supplementary angle.
WORK:
43 + (180 - 106) + 11x + 12x + 37 + 17x + 50 + 12x = 360
52x + 204 = 360
52x = 156
x = 3 degrees
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
This is the concept of geometry, given that the angle 52 and (2x) have been subtended by a circle, then:
2x=2(52)
2x=104
solving for x we get:
x=104/2
x=52
the answer is x=52°
