Area of triangle = base x height over 2
3 x 4 = 12
12 over 2 = 6
area = 6cm^2
20 is the area
And 18 is the perimeter

<h2>The missing measures of the angles are:</h2>

<u>Given</u>:

<em><u>Note the following:</u></em>
- An equilateral triangle has all its three angles equal to each other. Each angle =
.
- This implies that, since
is equilateral, therefore, 
- Base angles of an isosceles triangle are congruent to each other.
- This implies that, since
is isosceles, therefore, 
Applying the above stated, let's find the measure of each angle:
- Find

(an angle in an equilateral triangle equals 60 degrees)
- Find




- Find
and
(base angles of isosceles triangle WZY)


(base angles of isosceles triangle are congruent)
Therefore,

- Find


Substitute

The missing measures of the angles are:

Answer:
B) 120
Step-by-step explanation:
m = miles
$98=$80+$0.15m
$98-$80=$80-$80+$0.15m
$18=$0.15m
$18/$0.15=$0.15m/$0.15
120=m
Juliet drove 120 miles for $98.
(this is a good explanation, I guess)
