Answer:
187
Step-by-step explanation:
A number m is such that when it is divided by 30, 36 and 45 the remainder is always 7.
We should first find the LCM of 30, 36 and 45
We get that the LCM of the three numbers is 280 (working attached).
So now;
= 6
= 5
= 4
But we need a number that leaves a remainder of 7 so we add 7 to 180 to get; 180 + 7 = 187.
Ramp² = 19² + 4²
ramp² = 361 + 16
ramp² = 377

***************************************************************************
Incidentally, the angle of the ramp would be
tan (angle) = 4 / 19
tan (angle) =

It should be " b "
That should be right but u may want to wait for others to respond to this to make sure
