Answer:
C
Step-by-step explanation:
The reason we can use this method is because we are given a composite figure with a house shape with one triangle on top. We can use the guidance of the dotted lines to make out that a rectangle can be used to find the figure. We can see that apart from the figure, there are two congruent triangles. To find the area we would do -
First find the missing height of the smaller triangles. We would use the pythagorean theorem to find that the missing height is√5
We could do 8(4) = 32 to find the area of the rectangle.
Then, we could do 2√5/2 to find one missing triangle. We could then add the triangles to find the measures of the combined triangles as 2√5. Then, we could do 32 - 2√5 to find the area as 27.5.
Hope this helps :)
Answer:
If two sides of a triangle are unequal, then the measures of the angles opposite these sides are unequal, and the greater angle is opposite the greater side.

Answer:
Step-by-step explanation:
We are given the following in the question:
Cost of sending a mail =
30 cents for 1 ounce or less.
28 cents for each additional ounce or fraction of an ounce.
Let x represent the weight of mail. Let P(x) represents the cost in cents.
Weight of mail between 0 and 1 ounces
Weight of mail between 1 and 2 ounces
Weight of mail between 2 and 3 ounces
Thus, we can write the piecewise function for cost in the following manner:
where x is in ounces and P(x) is the cost in cents.
