Each day his study time is increasing. Find a common denominator, in this case 8
1/4 = 2/8
5/8 = 5/8
1 = 8/8
So he went from
2/8 to 5/8 to 8/8 which is an increase of 3/8 each day. If this pattern continues Thursday would be 11/8 and Friday 14/8.
14/8 = 1 6/8 = 1 3/4 hours
(an hour and 45 minutes)
225, the square root of 225 is 15
Answer:
140°
Step-by-step explanation:
The sum of angle of a triangle is equal to 180°.
Two of the angles measured 20°.
We need to find the measure of the third angle of Nora’s triangle. let the third angle is x. So,
20+20+x = 180
40+x = 180
x = 180-40
x = 140°
So, the third angle of the triangle is 140°.
