Step-by-step explanation:
According phythagorous theorem,
x²=(12)²+(5)²
x²=144+25
x= root of 169
x=13
Answer:
Step-by-step explanation:
The two base angles are equal.
The vertex angle is 8x
The two base angles are 5x + 5x
The sum of all three angles = 180 degrees (all triangles make 180 degrees when their interior angles are added).
5x + 5x + 8x = 180
18x = 180
x = 180/18
x = 10
Therefore the vertex angle is 8*10 = 80 degrees
One of the base angles = 10* 5 = 50 degrees
The other base angle = 50 because the triangle is isosceles.
80 because if you multiply all them you would get 64,000 then divide it
0.24 as a fraction equals 6/25
