Actually welcome to the concept of the Angle sum property...
The Angle sum property of a Quadilatetal =》
m/_A + m/_B + m/_C + m/_ D = 360°
Thus adding all the angles we get as....
=》 X + X + X+ 15° + X + 45° = 360°
=》 4X + 60° = 360°
thus ..4X = 360 - 60 = 300
Thus .. 4X = 300
X = 300 ÷ 4 =》 75°
X = 75°
Answer:
1000000000000000000000+10000000000000000000000 :)
Step-by-step:
If the number is 3.8333333.... then
X=3.83333....
10X = 38.3333.....
10X - X
38.3333....
- 3.8333....
= 34.5
so 9X = 34.5
X = 34.5/9
Multiple both top and bottom by 2 to get rid of decimal.
69/18
Normalize it to get rid of improper fraction.
3 15/18
Simplify
3 5/6
If the number is 3.838383838383.... then
X = 3.83838383...
100X = 383.83838383...
100X - X = 99X
383.83838383...
3.83838383...
380
99X = 380
X = 380/99
X = 3 83/99
The answer is 51°.
The top two lines are parallel to each other. Therefore alternate interior angles theorem applies. The bottom right corner that is underneath the line (for lack of a better description) is also 58°.
We also know that a triangle equals 180°. So 58+71= 129°.
So to find that missing angle we subtract 129 from 180 to get the 51°.
