Answer:
∠ADB = γ/2 +90°
Step-by-step explanation:
Here's one way to show the measure of ∠ADB.
∠ADB = 180° - (α + β) . . . . . sum of angles in ΔABD
∠ADB + (2α +β) + γ + (2β +α) = 360° . . . . . sum of angles in DXCY
Substituting for (α + β) in the second equation, we get ...
∠ADB + 3(180° - ∠ADB) + γ = 360°
180° + γ = 2(∠ADB) . . . . . . add 2(∠ADB)-360°
∠ADB = γ/2 + 90° . . . . . . . divide by 2
_____
To find angles CXD and CYD, we observe that these are exterior angles to triangles AXB and AYB, respectively. As such, those angles are equal to the sum of the remote interior angles, taking into account that AY and BX are angle bisectors.
Answer:
25
Step-by-step explanation:100 percent of 100 is 100 so 25 percent is 25
Answer:
x = 23 degress
Step-by-step explanation:
(x + 2) + 65 = 90
x + 2 = 25
<u>x = 23 degress</u>
I wanna say 10 or ether -10 since if it was subtracted from 2 then it would equal -8
just put a dot on the number line where 0, 3, and -3 are
