Answer: B. 7 and 10 ft
Explanation:
The first thing to do is to look at the triangle’s angles. One of them is missing right? So you need to find that missing angle. All the angles in a triangle add up to 180 degrees. Therefore you need to add 68 and 47. Your total must be subtracted by 180.
Your problem will look like this
68+47=115
180-115=65
Your missing angle is 65The angle correspond to the sides. You need to look at the opposite of the angle to figure out the number of the side.
For example Angle A opposite = 7
Angle B opposite is 10
notice that Angle B degree is 68 which is the largest degree. And Angle A degree is 47 which is the smallest degree.
The largest degree will always be equal to the largest side
The smallest degree will equal to the smallest side
