The answer is C. 45. Here's the work to prove it: c = correct answer, i = incorrect answer;
-2(c + i = 50)
2c - 3i = 75
-2c - 2i = -100
-5i/-5 = -25/-5
i = 5
c + 5 - 5 = 50 - 5
c = 45
Answer:D
Step-by-step explanation:
1 Answer. Suryin =) . 96√3 cm. Explanation: Area of regular hexagon : A=3√32a2. a is the side which is 8 cm. A=3√32(82). A=3√32(64). A= 192√32.
Remember that perimeter is the sum of the lengths of the sides. The way to find the length of the sides is
where
is one endpoint of one line, while
is the other endpoint of the same line. Repeat this formula for each side and add them all together to get your perimeter
Answer:
y=27
Step-by-step explanation:
Fact 1: The sum of two adjacent angles formed by the intersection of two lines is 180.
So, x+146=180
=>x=34
Fact 2: The sum of the inscribed angles in a triangle is 180.
So, (5y+3)+(4y+8)+34=180
=>5y=180-45
=>5y=135
=>y=27
