Answer:
h = 60 ; x = 25
Step-by-step explanation:
You are going to want to use Pythagorean Theorem to solve these.
Pythagorean Theorem: a² + b² = c²
h² + 144² = 156²
h² + 20736 = 24336
h² = 3600
h = 60
x² + 60² = 65²
x² + 3600 = 4225
x² = 625
x = 25
12345678910111213
12 and 13 are consecutive numbers
12+13=25
hence, 12 and 13 are your answers
The way i do it, is sort of like this :
Is 7 a factor of 42?
Is 5 a factor of 42?
7 is a factor of 42.
It must be in multiples of 7!
Therefore, we have 5 on the other side, which makes it 5 x 7 = 35
$25 times 45 equals $1125. Twice as many students as adults so, 45x2=90 90x$12= $1080 $1125+1080=$2205
