It depends, if the two sides given are adjacent to each other then yes. but you are given two opposite sides then no, because you don't know the length of one of the sides, thus not being able to calculate the perimeter
Answer: You are smart, figure it out yourself
Step-by-step explanation:
So all the angles of triangle add up to 180 degrees. So you add up the the two other sides and subtract 180 by the answer.
61 + 58 = 119
180 - 119 = 61
So, you’re answer would be 61 degrees. Hope that helped :)
Answer:
The width of the rectangle is 2.3 m
Step-by-step explanation:
Now, when we are asked to find the area of the rectangle, we will use the formula: 
. We should be given with at least two values, and then we can use the above formula and can find the third variable.
Now, we are given that the area of a rectangle is 12.65 
and the length measures 5.5 m
So the width is given as:
So this is the required with of the rectangle.
Answer:
