Answer:
$70.80
Step-by-step explanation:
60 x 18% = 10.80
$60.00 + $10.80 = $70.80
Answer:
x = 20°
y = 30
Step-by-step explanation:
The triangle given on close inspection, it is an equilateral triangle.
Each angle in an equilateral triangle is equal. Likewise, each side is equal.
Thus;
16 + y = 46
y = 46 - 16
y = 30
The triangle that has angle 80°, the other complete angle is 60° because it's an angle of an equilateral triangle.
Thus, the smaller angle there is;
180 - (80 + 60) = 40°
Because sum of angles in a triangle is 180°
Now, x + 40 = 60°
Since that's also an angle of an equilateral triangle.
x = 60 - 40
x = 20°
6 to the third power would be 6x6x6 which equals 216. All you do to find the power is multiply the number by its self the amount of times it asks like 4 to the second power would be 16 and 8 to the 4 power would be 4096
