Step-by-step explanation:
Answer:
55m
Step-by-step explanation:
a²+b²=c²
19 x 19 = 361
52 x 52 = 2704
2704 + 361= 3065
the square root of 3065 is 55.4 so round that to 55.
0.75
to find the decimal of a fraction divide the top number by the bottom number so 3 divided by for; aka the numerator by the denominator
Let the length of second side be x" ,
So,
Length of first side = 2" shorter than second = ( x - 2 )"
Length of third side = 5" longer than second = ( x + 5 )"
=×=×=×=×=×=×=×=×=×=×=×=×=×=×=×=×=
Given, perimeter = 33"
= > first side + second side + third side = 33"
= > ( x - 2 ) + x + ( x + 5 ) = 33
= > x - 2 + x + x + 5 = 33
= > 3x + 3 = 33
= > 3x = 30
= > x = 10
Hence, length of each side is
First side = ( x - 2 )" = ( 10 - 2 )" = 8 inches
Second side = x " = 10 inches
Third side = ( x + 5 )" = ( 10 + 5 )" = 15 inches
