Point B lies on AC between
Alecsey [184]

Answer:

A___B___C

AC = AB+ BC

3x +12 = ( 14) + (3-2x)

3x + 12 = – 2x + 17

3x + 2x = 17 - 12

5x = 5

x=5/5

x = 1

AC = 3x + 12 = 3(1) + 12 = 3 + 12= 15

I hope I helped you^_^

Which best explains whether a triangle with side lengths 5cm , 13cm and 12 cm is a right triangle the triangle is a right
Brrunno [24]

Answer:

Right triangle.

Step-by-step explanation:

We are asked to determine whether the given side lengths are sides of a right triangle or not.

We know that side lengths of a right triangle are Pythagoras triplets. The square of the longest must be equal to sum of squares of other sides.

Let us check sides of our given triangle.

13^2=5^2+12^2

169=25+144

169=169

Since both sides of equation are equal, therefore, the given side lengths are sides of a right triangle.
