You have a semicircle attached to a trapezium
Area of semicircle = 1/2 Pi r^2 = 1/2 + pi * 4^2 = 25.13 ( note r = 1/2 * 8 = 4)
Area of the trapezium = h/2 ( sum of 2 parallel sides) = 1/2 * 6 * (13 + 8)
= 63
Total area = 63 + 25.13 = 88.1 to nearest tenth
The answer of this problem is 17
Answer:
a) #4 vertical angles are congruent
b) # 1 ∠3 ≅ ∠7
c) # 6 Transitive property
Step-by-step explanation:
a. Vertical angles - opposite angles that are equal.
b. corresponding angles - in the same place but on different parallel lines
and are equal.
c. a = b, b = c so a = c
First, the range is all about the y-values, so the set notation needs to have the form:
{ y : y __________}
Because of that, you can eliminate the first and third options that use “x”. Using x would reference the domain.
Second, the range is the set of all y-values used in the function. You only include y-values in the range, so you’d only include 8, 3, -2, and -7 in your answer.
That means it’s the second answer.
Side note:
Some areas would use the notation { y | y = -7, -2, 3, 8}, using “|” instead of “:” in the set notation.f
