Answer:
The first one. 4 times square root of 3.
Step-by-step explanation:
The side of the equilateral triangle that represents the height of the triangle will have a length of because it will be opposite the 60o angle. To calculate the area of the triangle, multiply the base (one side of the equilateral triangle) and the height (the perpendicular bisector) and divide by two.

Answer: 4
Step-by-step explanation:
(1,3) means that x = 1 and y = 3. Let's make substitutions to see what happens with the inequality
5*x + y < -3
5*1 + y < -3 ... replace x with 1
5*1 + 3 < -3 ... replace y with 3
5 + 3 < -3
8 < -3
This is false. The number 8 is NOT smaller than -3.
So (1,3) is NOT a solution
Answer: Choice A) No
Answer:
40 degrees
Step-by-step explanation:
x and 40 (degrees) are "vertical angles" and are thus equal. So x = 40 degrees.
