Answer:
x ≈ 2.76
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan78° = 
= 
= 
( multiply both sides by x )
x × tan78° = 13 ( divide both sides by tan78° )
x = 
≈ 2.76 ( to 2 dec. places )
Finishing the angles of the smaller triangle if E is 90 and F is 30 then G needs to be 180-90-30 = 60 degrees.
Angles G and C are supplementary angles which need to equal 180 degrees
Angle c = 180-g = 180-60 = 120
Angle c = 120 degrees.

Answer:
$49.72
Step-by-step explanation:
The tip is 11% of the price of the pizza.
The price of the pizza is $452.
The tip is 11% of $452.
<em>To find a percent of a number, change the percent to a decimal and multiply by the number. To change a percent to a decimal, divide the percent by 100 which is the same as moving the decimal point two places to the left.</em>
11% of $452 =
= 0.11 * $452
= $49.72
Answer: $49.72
