A triangle with lengths 5, 12, and 13 is a Pythagorean triple
The approximate acute angles are 22.6° and 67.4°
Pythagorean triple 
Pythagorean triple consist of positive number(a, b, c) such that it obeys the rule:
A triangle whose sides form a Pythagorean triple is called a right angle triangle.
The longest side is the hypotenuse side.
Therefore,
- 5² + 12² 
- 25 + 144 = 169
- √169  = 13
Therefore,
5² + 12² = 13²
 This means the triangle is a Pythagorean triple.
<h3>Acute angles</h3>
Acute angles are angles that are less than 90 degrees. This means the other two angles are acute angle.
Therefore, let's find them
- tan ∅ = opposite / adjacent = tan ∅ = 5 / 12 = ∅ = 22.6198649155 = 22.6°
- 180 - 22.6 - 90 = 67.4°

Hi there!
The answer would be B. The number 3 was rolled 5 times in 36 trials.
This shows that out of all 36 times the dice was rolled the number 3 faced upwards 5 times.
Hope this helps !
        
                    
             
        
        
        
Answer: A = 1032 in² 
Step-by-step explanation:
two sides each of rectangles
2(10)(18) + 2(10)(12) + 2(12)(18) = 1032 in²
