Answer:
∠A = 44°
Step-by-step explanation:
In order to find the measure of angle A, you need to know the value of the variable x. This means you need some relation that you can solve to find x.
Happily, that relation is "the sum of angles in a triangle is 180°." This means ...
84° +(x +59)° +(x +51)° = 180°
(2x + 194)° = 180° . . . collect terms
2x = -14 . . . . . . . . . . divide by °, and subtract 194
x = -7 . . . . . . . . . . . .divide by 2
Now, the measure of angle A is ...
∠A = (x +51)° = (-7 +51)°
∠A = 44°

Explanation:
120 % = 1.2
If Maxine is correct, then she spent 1.2
times the hours she did homework than last week.

15 hours ⋅ 1.2 = 18.0 hours = 18 hours
Maxine is correct
The LCM of 20 and 300 is 300.
<h3>How to find the LCM?</h3>
The multiple of 20 will be:
20 = 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300
The multiple of 300 will be:
300 = 300, 600, 900
Therefore, the lowest common multiple of 20 and 300 is 300.
