Answer:
±5
Step-by-step explanation:
Apply the Pythagorean Theorem:
x^2 + 12^2 = 13^2, or
x^2 = 169 - 144 = 25
The possible y-coordinate vaues are ±√25, or ±5
The angles are in the ratio of 5:6:9.
Let the angles be represented by:
5x, 6x, and 9x.
The sum of the interior angles of a triangle is 180.
5x + 6x + 9x = 180
20x = 180
x = 9
The angles are 5*9 = 45,
6*9 = 54,
and
9*9 = 81.
Answer:
the answer is a and d
Step-by-step explanation:
6 + 6 + 2 +2 = 16
3 + 3 + 5 + 5 = 16
to find perimeter, double each factor and add :)
Answer: Nope.
Step-by-step explanation: All circles are round and have no corners. Therefore, they cannot have any angles - right angles included.
