Answer:
36
Step-by-step explanation:
a² + b² = c²
a² + 77² = 85²
a² + 5929 = 7225
a² = 1296
a = 36
This is kinda hard to explain but I'll try my best. Here's a tip, the fractions that are on the ruler really mean 10,20,30,40,50,60,70,80,90, and 100. So, when you look at the decimals on number 7, you have to try to turn them into fractions in your head. For example, 0.9 is actually 9/10 or 90.

If you would like to solve the following equations, you can calculate it using these steps:
1) x% of 125 cm is 87.5 cm
x% * 125 = 87.5
x/100 * 125 = 87.5 /*100/125
x = 87.5 * 100 / 125
x = 70%
2) y% of 132 days is 125.4 days
y% * 132 = 125.4
y/100 * 132 = 125.4 /*100/132
y = 125.4 * 100 / 132
y = 95%
