Answer:
60
Step-by-step explanation:
48 multiplied by 25% = 48 multiplied by 0.25 = 12
48 plus the increase = 60
The answer would be the second option, 13.0 cm.
To find the missing length of the leg, you would use the pythagorean theorem and substitute your inputs in.
a^2+b^2=c^2
11^2+b^2=17^2
121+b^2=289
b^2=168
b=12.96
b=13.0 cm (rounded up)
The answer is 1.6632. Using a calculator will help you out a lot :)
Still, hope this helps :)
