Answer: 1. 1,0 2. -1,9 3.-20
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
Find the missing angle:
180⁰ - 82⁰ = 98⁰
Find the sum of the angles given without the missing angle:
180⁰ - 98⁰ = 82⁰
The sum of both the angles is 82⁰
Write an equation:
5x + 8 + 6x + 8 = 82⁰
Collect the like terms together
11x + 16⁰ = 82⁰
Subtract 16⁰ from both sides
11x = 66⁰
Divide by 11 on both sides
x = 6⁰
Answer: The correct point is (1, 0)
In polar coordinates, the first number is the distance from the origin in any direction. The second number is an angle measurement that tells us the direction to go from the origin.
Therefore, we have to move -1 one unit (or backwards) from the origin. Now, all we need to know is the direction to move.
The second number is 180, so we make an angle of 180 degrees and move in that direction.
But where do we start?
We always start from the origin straight right along the x-axis. That is degrees 0. So a 180 degree angle would move us left along the x-axis. But remember, we are moving back 1 space, so we will end up at (1, 0).
D this because 7 minus 1 is 6
