Answer:
To find c° go with <em><u>Triangle Sum Theorem</u></em> .
To find d° go with <em><u>Supplementary Angle with 58°.</u></em>
To find a° go with <em><u>Transverse Angles</u></em><em><u>.</u></em>
To find b° go with <em><u>Transverse Angles .</u></em>
Step-by-step explanation:
c° = 180- 58 - 48 = <em><u>74</u></em><em><u>°</u></em>
b° = <em><u>48</u></em><em><u>°</u></em>
d° = 180 - 58 = <em><u>122</u></em><em><u>°</u></em>
a° = <em><u>58</u></em><em><u>°</u></em>
1 because with the term just being x^3, the coefficient that goes with just an x is always 1.

Answer:
<u>The perimeter of the square is option E. 16√5 mm.</u>
<u>The area of the square is option A. 80 mm².</u>
Step-by-step explanation:
1. Let's calculate the perimeter of this square:
The perimeter of a square is the sum of its side 4 times, thus:
Perimeter = 4√5 + 4√5 + 4√5 + 4√5
<u>Perimeter = 16 √5</u>
<u>Perimeter = 4 * 4√5 = 16√5</u>
<u>The correct answer is option E. 16√5 mm</u>
2. Let's calculate the area of this square:
The area of a square is the length of its side squared, thus:
Area = (4√5)²
Area = 4√5 * 4√5
Area = (4 * 4 * √5 * √5)
Area = 16 * 5 = 80
<u>The correct answer is A. 80 mm²</u>
X has to be inside the radical.
It would be
Simplify the radical by breaking the radicand up into a product of known factors.
