Answer:
72
Step-by-step explanation:
18*4
12*6
8*9
Both lines are parallel so using the bottom line you are given angle 7 as being 80 degrees. Angle 5 and 7 form a straight line which is 180 degrees so angle 5 would be 180-80 = 100 degrees.
Angle 1 is the same as angle 5 so angle 1 is 100 degrees.
Answer: 100 degrees
Answer:
127
Step-by-step explanation:
(n-2)180
(5-2)180
=540 for total angle
540-90(3)-143
=127
c. 5/6 cups
Step-by-step explanation:
1 2/3 = 5/3
5/3= 1.666
1.66÷2= 0.833
When we divide. the number should equal 0.833
8/3= 2.66 nope
10/3= 3.33 nope
5/6= 0.833 yes
6/5= 1.2 nope
Answer is 40. A triangle equals 180 so all you do is subtract 65 and 75 from 180 to get your answer.
