Answer:
True
Step-by-step explanation:
If the triangle was a right angled triangle then we can prove it using the Pythagoras theorem: c² = a² + b²
c is the largest side and a and b are the two smaller sides of the triangle.
So if this is true then √72² + 154² should be 170:
170² = 72² + 154²
28900 = 5184 + 23716
28900 = 28900
So we have proved using Pythagoras theorem that the triangle is a right angled triangle.
Answer:
18 1/2
Step-by-step explanation:
3 7/10 x 5 = 18 1/2
Answer:
y=3/5x+3
Step-by-step explanation:
m=(9-6)/(10-5)=3/5
y=3/5(x-5)+6
y=3/5x+3
I think (0,4) in this problem is weird.
Answer:
A. 3 and a half hours (3 hours 30 minutes)
B. 72 dollars
Step-by-step explanation:
A. first do 512-92 = 420
420/120 = 3.5 hours
B. 2 hours = 240 dollars
312 - 240 = 72 dollars for the parts
