Answer:
Isosceles triangle.
Step-by-step explanation:
On the basis of the lengths of the sides of a triangle, below are three types of triangles.
Equilateral triangle: The triangle in which the lengths of all sides are equal.
Isosceles triangle: The triangle in which the lengths of any two sides are equal.
scalene triangle: The triangle in which the lengths all the three sides are different.
Here, the length of the sides are 24 24 and 4.
Since, two sides are equal in length.
Hence, it is an Isosceles triangle.

Answer:
(-3, 0)
(0, 3)
(1, 4)
Step-by-step explanation:
It’s easier if you make an equation like this!
Start by finding the slope using two points
m = slope
m = y2 - y1/x2 - x1
For right now, I’m going to have to use two points from the graph.
Points: (-5, -2) and (0, 3)
m = 3 - -2/0 - -5
m = 5/5
m = 1
Now find the y-intercept (located where x coordinate is 0)
y-intercept = 3
Now make the equation of a line that has a slope of 1 and a y-intercept of 3
y = x + 3
Now use any point to see if it is a point on the graph.
y = x + 3
Point: (2, 5)
5 = 2 + 3
5 = 5
Therefore it is a point
y = x + 3
Point: (-3, 0)
0 = -3 + 3
0 = 0
y = x + 3
Point: (2, 4)
4 = 2 + 3
4 = 5
Answer:
x = 12
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 81 = 15²
x² + 81 = 225 ( subtract 81 from both sides )
x² = 144 ( take the square root of both sides )
x = = 12
