•sum of the angles in a triangle = 180°
•sum of the angle in a quadrilateral = 360°
•opposite angles are equal
•for two parallel lines and a transversal, corresponding angles are equal, and alternate angles are equal.
•If it already has an angle for a triangle subtract that by 180 and divide it by two you have the other two angle, if you already have two angles on a triangle add those together and subtract from 180 thats the last angle, same for a quadrilateral but you subtract by 360 instead.
Answer:
∠1=a+b/2
∠1=37+25/2
∠1=31
Answer: C) 31

Answer:
10
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation:
There are six options in total and two if these are yellow. therefore the answr us 2/6 which simplifies to 1/3 meaning the answer is 1/3.
For the average to be 90,
(99 + 93 + x) / 3 = 90
or 192 + x = 270
or x = 270 - 192 = 78
Jim must score at least 78 in the third test.
