A triangle has two sides measuring 8.5 cm and 15 cm. What are the least and greatest whole number possibilities for the third si
1 answer:
Answer:
least number is 7 and greatest number is 23
Step-by-step explanation:
A triangle has two sides measuring 8.5 cm and 15 cm
a=8.5, b= 15cm
To form a triangle , the sides should satisfy the following conditions
a+b>c and a+c>b
Plug in the values
Plug in the values
subtract 8.5 from both sides
So c lies between 6.5 and 23.5
least number is 7 and greatest number is 23

Answer:
Step-by-step explanation:
The midpoint of two points is the average of the x coordinates and the average of the y coordinates.
Given
A(3, -1)
and we let the other end point B be B(x,y)
and midpoint is (-7,10)
So, the average of 3 and x is -7, and
the average of -1 and y is 10
We can solve for x first:
and now solving for y:
So, the other point B is:
Answer: 1) c 2) a 3) d

Reference angle is the angle measurement from the x-axis. <em>There is no such thing as a negative reference angle.</em>
-183° is 3° from the x-axis so the reference angle is

Coterminal means the same angle location after one or more<em> </em>rotations either clockwise or counter-clockwise.
To find these angles, add <em>or subtract</em> 360° from the given angle to find one rotation, add <em>or subtract</em> 2(360°) from the given angle to find two rotations, etc.
To find ALL of the coterminals, add <em>or subtract</em> 360° as many times as the number of rotations. Rotations can only be integers. In other words, you can only have ± 1, 2, 3, ... rotations. You cannot have a fraction of a rotation.
Given: 203°
Coterminal angles: 203° ± k360°, k ∈ <em>I</em>
