Step-by-step explanation:
10 + 5x = 10 + 5(15)
= 10 + 75
= 85°
4x - 10 = 4(15) - 10
= 60 - 10
= 50°
6x - 5 = 6(15) - 5
= 90 - 5
= 85°

what is the side length of a square given the area to be 625m
Answers
Answer: 25 meters
Step-by-step explanation:
✓625 = 25
Answer:25
Step-by-step explanation:A square has equal length on all its sides, so the area of square is
Length x Length = 625
Which is
Length ^2 = 625
We want the number that when it times it’s self it’s 625
It can be done by square root of 625 which is 25. So the length of side is 25.
Or look at the prime factorization of 625 ( or just factors) and what number they can make up
Which is 5x5x5x5 = 625
They can make up
5^2 x 5^2 = 25 x 25 that is the “same” number
So the length is 25

What is the sum of the 12th square number and the 10th square number?
Answers
Answer:
12^2 is 144 and 10^2 is 100 :)
Step-by-step explanation:
12 * 12 = 144
10 * 10 = 100
The sum of the 12th square number and the 10th square number is 244. This problem is based on the principle of addition.
The principle of addition states that when two numbers are added together, their sum is a unique number which is not necessarily be divisible by either the numbers or their factors. The addition is inverse operation of the subtraction.
The square of 12th number is 12² = 12 × 12 = 144.
The square of 10th number is 10² = 10 × 10 = 100.
The sum of both numbers = 144 + 100 = 244.
Hence, the answer to the given problem is 244.
