Hopefully, I have read the problems right. The small writing is slightly blurry.
[1] Both 1 and 2 are equal to 70°
Angle 1 and Angle 2 will be equal to each other because they are vertical angles.
A straight line is 180°, so 180° - 110° = 70°
[2] Both 3 and 4 are equal to 99°
Again, Angle 3 and Angle 4 will be equal to each other because they are vertical angles.
We can solve for the other two angles by putting them equal to each other since they are also vertical angles.
3x - 15° = 2x + 17°
3x = 2x + 32°
x = 32°
-
2x + 17°
2(32)° + 17°
64° + 17°
81°
Also again, a straight line is 180°. 180° - 81° = 99°
[3] This one has too many subparts for Brainly.
As a hint, you will use the same methods above. Find vertical angles and use the degree of a straight line.
