Answer:
103°
Step-by-step explanation:
Let's take the 3rd angle as θ:
Since all the angles in a triangle add up to 180°,
57 + 20 + θ = 180
77 + θ = 180
θ = 180 - 77
= 103°
Hence, the third angle is 103°

The amount of calories Lucie will burn by jumping for 1 minute is 8 calories
Step-by-step explanation:
The given data values are;
Minutes
Calories Burned
40
320
80
640
120
960
160
1280
The value of calories burnt and the number of minutes of jump robe are seen to be directly proportional, such that we have;
40 minutes of jump rope will yield 320 calories burnt
Therefore we have;
1 minute of jump rope will yield 320/40 = 8 calories burnt
The amount of calories Lucie will burn by jumping for 1 minute = 8 calories.
