If the measures of the angles of a triangle are represented by 2x,3x -15 and 7x +15 the triangle is

1 answer:

7 0

To get the type of triangle mentioned we need to find the value of x first.
Sum of angles in a triangle add up to 180°, thus
2x+(3x-15)+(7x+15)=180
2x+3x-15+7x+15=180
12x=180
x=15°
thus the respective sizes will be:
2x=30°
3x-15=30°
7x+15=120°
Since the triangle has two congruent angles we conclude that the triangle is called Isosceles triangle

Answer:

8, 16, 64

Step-by-step explanation:

8 = 2^3 . . . a perfect cube

16 = 4^2 . . . a perfect square

32 = 2^5 . . . neither a cube nor a square

64 = 2^6 = 4^3 = 8^2 . . . both a perfect cube and a perfect square

128 = 2^7 . . . neither a cube nor a square
