Answer:
102 degrees.
Step-by-step explanation:
Because the 3.3's are congruent (the same), this triangle is isosceles.
A property of isosceles means that the two angles are congruent.
39+39= 78
This means that the last angle must be 180-78.
Answer:
4x^2−1
Step-by-step explanation:
$7.95 x h = $236.50
$7.95 x 18 = $143.10
$236.50 - $143.10 = $93.4
7.95 x h = $93.4
$93.4 / $7.95 = 11.7 hours
h = 12 hours
