Answer:
No
Step-by-step explanation:
Triangles have 180 degrees total. Once you take away 90 from it being a right triangle, you have 90 degrees left. For an angle to be right or obtuse it would have to be over 90 degrees, therefore, A right triangle has one right angle and two acute angles.
Answer:
24
Step-by-step explanation:
A^2+b^2=c^2
In this case C^2 is solved and we have to solve for the remaining leg.
7^2+b^2=25^2
49+b^2=625
625-49=576
sqrt 576 = 24
The height is 24
Answer:

Step-by-step explanation:
Given : Vertices of Triangle
,
and 
To find : Centroid of a triangle
The centroid of a triangle is the point of intersection of the three medians of the triangle.
The formula to calculate the centroid of a triangle is:

Where,
are the coordinates of the centroid
Substituting the values in the formula gives us:



Therefore, 
18a+15
making a subject of formular
a=18-15
=3
