The measure of the third angle of the triangle is 100°.
Since two angles are already provided in the problem. We just have to deduct the sum of these angles to get the angle measurement of the third angle.
35° + 45° = 80°
180° - 80° = 100°
Bear in mind that the sum of the interior angles of a triangle is always equal to 180°. So to find the missing measurement of every angle the equation should always be equal to 180°.
angle 1 + angle 2 + angle 3 = 180°
You should ask yourself: "Who are my readers?"
The preposition in this case is From while the prepositional phrase is From China as it consists of the preposition from and the noun China.
Thats cool i guess, whatever
