Answer:
63 degrees
Step-by-step explanation:
Since the angles are going counter-clockwise, angle 2 and angle 3 are supplementary, meaning that they add up to 180 degrees.
Since angle 2 is 117 degrees, 180 - 117 = 63. Therefore, angle 3 is 63 degrees
I’m assuming you mean -1/4 -4, and since you’re subtracting a negative by a negative, it would be -4 1/4(mixed number)
Answer:
3:2
Step-by-step explanation:
2 boys for every 3 girls
Use the distributive property.
1/7(105 + r) = 20
15 + (1/7)r = 20
Then subtract each side of the equation by 15.
15 + (1/7)r = 20
(1/7)r = 5
Divide both sides by 1/7.
(1/7)r = 5
r = 35
So, the answer to this question is r is equal to 35.
