Mary is wrong because ∠A = ∠B = 63°, while ∠C = x ≠ 63°
<h3>What is a
triangle?</h3>
A triangle is a polygon with three sides and three angles. Types of triangles are equilateral, isosceles and right angled.
An isosceles triangle is a triangle in which two sides and two angles are equal.
From the diagram:
∠A = ∠B (base angles)
Mary is wrong because ∠A = ∠B = 63°, while ∠C = x ≠ 63°

Answer:
Mean
Step-by-step explanation:
Mode:
Before adding 97 = 38
After adding 97 = 38
Mean:
Before adding 97 = 513/9 = 57
After adding 97 = 610/10 = 61
Median:
38, 38 , 38, 43, 54, 56, 70, 79, 97
Before adding 97 = 54
38, 38 , 38, 43, 54, 56, 70, 79, 97, 97
After adding 97 = 54 +56/2 = 110/2 = 55
It's simple, you just have to times everything. 5000 x 3.2% x 5 years. After calculating these, 3.2 is as 0.032 so there would be three decimal places. So then it will e 5000 x 0.032 x 5
