Answer:
length of side = 9
Step-by-step explanation:
This is a right angle triangle so we can use Pythagoras theorem. a^2 + b^2 = c^2
a^2 + 12^2 = 15^2
a^2 = (15^2) - (12^2)
a^2 = 225 - 144
a^2 = 81
a = square root of 81
a = 9
Answer:
8
Step-by-step explanation:
2 times 2 times 2=8
1st you have to take the common denominator which is 12. to turn the 3/4 into 12 you multiply by 3 because 4×3=12
what you do to the bottom you must do to the top so 3×3=9
you are left with 6/12÷9/12
flip and multiply so 6/12×12/9= 2/3
