4, 8, 10, 7, 3, 4... Those r in order from top to bottom! it's all about the simplification!
So all the angles in total are going to be 180 degrees.
7+9+10 = 18 (parts at all)
180/18=10 (1 part of the ratio)
Than to find all of the angles we multiply 1 part by 7, 9 and 10 separately
10*7= 70 degrees (1st angle)
10*9=90 degrees (2nd angle)
10*10=100 degrees (3rd angle)
Answer: 70, 90, 100
Answer:
1. 45
2. 105
3. 95
4. 85
Step-by-step explanation:
For problems 1 and 4:
Consecutive angles are supplementary in a parallelogram, which means they equal 180.
180 - 135 = 45
180 - 95 = 85
For problems 2 and 3:
Opposite angles are congruent or equal each other in a parallelogram,
You just add everything
20 + 11 + 9 + 9 + 4 + 4
= 31 + 9 + 9 + 4 + 4
= 40 + 9 + 4 + 4
= 49 + 4 + 4
= 53 + 4
= 57
So therefore ur answer is (A) 57 square yards.
