Find the area of the triangle. round the answer to the nearest tenth.

a.
7.8 square units
b.
8.9 square units
c.
19.3 square units
d.
38.5 square units

19.3 square units .

Step-by-step explanation:

∠D=∠F=52°

Opposite sides of equal angles are equal .

So, DE=EF =6.3

Now sum of all angles of triangle is 180°

So, ∠D+∠F+∠E = 180°

52°+52°+∠E =180°

104°+∠E =180°

∠E =180°-104°

∠E =76°

Now to find the length of DF we will use law of cosines

Now we are supposed to find the area of triangle

To calculate the area of given triangle we will use the heron's formula :

Where

a,b,c are the side lengths of triangle  

Now substitute the values :

Hence the area of the triangle is 19.2907 ≈19.3 square units .

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
