Answer:
D. 135.37 in²
Step-by-step explanation:
We have that the gift paper consists of two circles and a square.
Thus, we will need to find the area of the circles and the square.
Now, as the diameter of the circle = 4 inches
So, the radius of the circle = = 2 inches
Since, the area of a circle =
This implies that area of the two circles =
i.e. Area of the circles =
i.e. Area of the circles =
i.e. Area of the two circles = 25.133 in²
Further, one side of the square = 10.5 inches
Thus, the area of the square =
i.e. Area of the square =
i.e. Area of the square = 110.25 in²
So, the overall area of the gift paper = 25.133 + 110.25 = 135.37 in².
Hence, the amount of paper used by Angela is 135.37 in².
Two angles are said to be supplementary if their sum is 180 degrees. So, if x and y are supplementary angles, the formula is
We know that one of the angles (say x) is 98. So, the equation updates to
If we want to solve for the other angle, we can simply subtract 98 from both sides to get
