Large bag contains 14
30% of 14 is 3 / 10 times 14 which is 42 / 10 = 21 / 5 pounds of pretzels, in improper form, 4 and 1 / 5th of a pound or 4.2 pounds
Alright!
The formula of area of a triangle is base x height /2
so you're given the height and hypotenuse.
Do the reverse of the pythagorean theorem to find the base
a^2= c^2 -b^2
c^2 is the hypotenuse and b^2 is the height
a^2= 10^2 - 8^2
a^2 = 100 - 84
a^2 = 16
a= (square root the 16)
a= 4 cm
now put these numbers into the formula for area of a triangle
bxh / 2
(4x8)/ 2
= 16 cm squared !!
hope that makes sense :)
