Answer:
yes it's a right angle triangle
Step-by-step explanation:
Given the sides are in the ratio 3:4:5.
Let ABC be the given triangle.
Let the sides be 3x,4x and hypotenuse be 5x.
According to Pythagoras theorem,

Answer:
hope this helps
Step-by-step explanation:
Let a , b , c are three sides of a triangle
a : b : c = 3 : 4 : 5
a = 3x ,
b = 4x ,
c = 5x
a² = 9x²
b² = 16x²,
c² = 25x².
c² = a² + b²
by the pythagorean theorem,
a , b , c forms a right angled Triangle.

Answer:
i can see it
Step-by-step explanation:
You can get the number by dividing 19.2 by 0.40 The number is 19.2/0.40 = 48
1. 4 • (–3) • 5
so 4 x (-3) = -12 and then -12 x 5 = -60 2. (2.25 x 23) x 4 so (2.25 x 23) 51.75 and then 51.75 x4 = 207 4. 5 x 12 x (-2) so 5 x 12 = 60 and then 60 x (-2) = -120 5. 35(26)(0) = so 35 x 26 = 910 and then 910 x 0 = 0
