Atriangle has side lengths of 2 meters, 11 meters, and 11 meters. classify the triangle by the lengths of its sides.
a. scalene triangle
b. isosceles triangle
c. equilateral triangle
d. obtuse triangle

It would be b. isosceles triangle because two sides are the same

Here, Two sides are equal of length 11 meters, so it would be: "isosceles triangle"

In short, Your Answer would be Option B

Hope this helps!

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
