If the sides of the triangle have lengths of: 2, 1, and 2√3
Then, the triangle is a
c. neither a 45-45-90 triangle nor a 30-60-90 triangle.
Looking at the lengths, if the triangle is a right triangle
2 and 1 must be the measure of the legs
2√3, the measure of the hypotenuse
If we use the Pythagorean theorem,
2^2 + 1^2 = (2√3)^2
5 = 12 (not correct)
Therefore, the triangle is not a right trangle
Answer:
-16
Step-by-step explanation:
distribute the 4: 4x-8=-72
add 8 to both sides: 4x=-64
divide by 4: x+-16
4 is the rotational symmetry
Answer:
x =
<u><em>OR</em></u>
x =
Step-by-step explanation:
<em>Cross Multiplying</em>
x × 8 = 5 × 3
8x = 15
<em>Dividing both sides by 8</em>
x =
<u><em>OR</em></u>
x =
