when running a line, in a right-triangle, from the 90° angle perpendicular to its opposite side, we will end up with three similar triangles, one Small, one Medium and a containing Large one. Check the picture below.

Answer:
A, B, C
Step-by-step explanation:
Step 1: "AB ≅ DE, AC ≅ DF, and ∠A ≅ ∠D"
A. Given.
This is the information that was given in the problem statement.
Step 2: "ΔABC ≅ ΔDEF"
B. Side-Angle-Side Postulate (SAS)
The SAS postulate says that if two triangles have a pair of congruent angles between two pairs of congruent sides, then the triangles must be congruent. From the previous step, we can conclude the triangles are congruent.
Step 3: "∠C ≅ ∠F"
C. Corresponding parts of congruent triangles are congruent (CPCTC)
In Step 2, we established the triangles are congruent. So now we can conclude that the corresponding angles are congruent.
Answer:
<em>f = g/ g+1</em>
Step-by-step explanation:
Remove Parenthesis.
<em>fg - 1 x 5 = g - 1 x f - 1 x 5</em>
Cancel <em>-1 x 5</em> on both sides.
<em>fg = g - 1 x f</em>
Simplify <em>1 x f</em> to f.
<em>fg = g - f</em>
Add <em>f </em>to both sides.
<em>fg + f = g</em>
Factor out the common term <em>f.</em>
<em>f (g + 1) = g</em>
Divide both sides by <em>g + 1</em>
<em>f = g/ g + 1</em>
To solve this is you have to find the price per ounce for each item by simply dividing the price by the ounces.
For the oat cereal divide $3.90 by 15
3.90/15
.26 per ounce
For the rice cereal divide $3.30 by 11
3.30/11
.30 per ounce
The oat cereal costs less per ounce since it is only .26 per ounce whereas the rice cereal is .30 per ounce.
Hope this helps!
