Step-by-step explanation:
5²=4²+x²
25=16+x²
25-16=x²
9=x²
√9=√x²
3=x
A
Answer:
y=65
x=50
Step-by-step explanation:
exterior angle of a triamgle is equal to sum of two interior angles
so
2y=130(as it is isosceles triangle)
y=65
we know y+y+x=180(sum of all angles of triangle)and (vertically opposite angle)
therefore, x=50
Ok this is a bit complicated.
Total: 114 days
114 divided by 3 equals 38
38 times 2 equals 76
76 books, I think.
You should try this (20+7)+(10+5)=42
