Answer:
Supplementary Angle's Theorem
Step-by-step explanation:
The supplementary angle theorem states that if two angles are said to be supplementary to the same angle, then the two angles are said to be congruent.
<span>The Pythagorean Theorem.If a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse, then the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse</span>
Answer:
11 and 2/3.
Step-by-step explanation:
6 and 3/12 = 72/12 + 3/12 = 75/12.
5 and 5/12 = 60/12 + 5/12 = 65/12.
75/12 + 65/12 = 140 / 12 = 70 / 6 = 35 / 3 = 11 and 2/3.
Hope this helps!
Answer:
B. Opposite angles add up to 180 degrees.
Step-by-step explanation:
Answer Choice B is incorrect because opposite angles are actually congruent. However, adjacent angles of a parallelogram do add up to 180 degrees.
The formula you need to use is a^2 + b^2 = c^2. A is the side of 3 and B is the side of 7, so 3^2 + 7^2 = c^2.
9 + 49 = c^2
58 = c^2
√58 = C
So your answer is C. √58. I hope this helps!
