First, find the area of the base (the triangle) and then multiply it by the height
to find the area of the triangle you need to know the height. cut the triangle in half and you get a right triangle, from there you can use the Pythagorean theorem. remember since you cut the triangle in half you have to divide one of the sides by 2
a^2 + b^2 = c^2 (plug in known information)
a^2 + (7.5)^2 = (15)^2 (solve, first solve the exponents)
a^2 + 56.25 = 225 (subtract 56.25 on both sides)
a^2 = 168.75 (solve for a, put 168.75 under the square root)
then once you find the area multiply by the known height
Basically you want to find an equivalent fraction for 3/5 in the answer choices.
12/20 equals 3/5 because 3/5 x 4/4 (or 1) = 12/20
answer: 4

The volume of Earth is about 
Dividing Saturn's volume by Earth's volume

Answer:
Step-by-step explanation:
<u>∠A≅∠E, ∠B≅∠F and ∠C is common and congruent to itself, therefore</u>
- ΔABC ~ ΔEFC by AA similarity
<u>Ratio of corresponding sides is same. Get the equation below and solve for x:</u>
- EC/AC = CF/CB
- x/17 = (16+22)/16
- x/17 = 38/16
- x/17 = 19/8
- x = 17*19/8
- x = 40.375
