Answer:
No.
Step-by-step explanation:
Since we know the side lengths of the triangle, we can figure out whether or not this is a Pythagorean triple.
Pythagorean theorem: a^2 + b^2 = c^2
a and b are both smaller than c.
So,
8^2 = 64.
13^2 = 169.
15^2 = 225.
64 + 169 = 233.
233 is not equal to 225.
Therefore, this is not a right triangle.
Answer:

Step-by-step explanation:
24y = 7
Our primary objective here is to get y on it's own side, without any numbers attached.
Since a 24 is attached to the y, we have to divide the 24y by 24.


Remember that whatever we do to one side, we MUST do to the other.

Since
can't be simplified, that would be our answer.

Answer:
45
Step-by-step explanation:
Step-by-step explanation:
In a right angle triangle one angle is 90°
w.k.t sum of angles in a triangle is 180°
thus, 2x+15+x+90°=180°
3x+105°=180°
3x=75°
x= 75/3=25°
Hope this helps you.
