Answer:
Not really
Step-by-step explanation:
NOT NECESSARILY would a triangle be equilateral if one of its angles is 60 degrees. To be an equilateral triangle (a triangle in which all 3 sides have the same length), all 3 angles of the triangle would have to be 60°-angles; however, the triangle could be a 30°-60°-90° right triangle in which the side opposite the 30 degree angle is one-half as long as the hypotenuse, and the length of the side opposite the 60 degree angle is √3/2 as long as the hypotenuse. Another of possibly many examples would be a triangle with angles of 60°, 40°, and 80° which has opposite sides of lengths 2, 1.4845 (rounded to 4 decimal places), and 2.2743 (rounded to 4 decimal places), respectively, the last two of which were determined by using the Law of Sines: "In any triangle ABC, having sides of length a, b, and c, the following relationships are true: a/sin A = b/sin B = c/sin C."¹
Answer:
The perimeter is 70
Step-by-step explanation:
Isosceles means all sides same length. So to start out, you need to firgure out x so you can do let's say 3x-5=19x, or you can do 2x=19-x, or an combination pretty much. Once completing this, you find that x=14. Now all you have to do is plug 14 into all the x spots, and add everything together

Answer:
the answer to the whole equation is x=30.
Step-by-step explanation:
do 2/3(2) and -1/2(3)
4/6x and -3/6x
add the -3/6x to the other side
7/6x or 1 and 1/6x=5
times both by 6
x=30
does 22cm is the diameter ??
Here, we need to check for all pairs by substituting the value of x & y,
1) 11 + 11 = -14(-2-2)
sides are not equal.
2) -11 + 11 = -14(2 - 2)
0 = 0
sides are equal.
In Short, Your Answer would be Option 2
Hope this helps!
