Answer: A) 57</h3>
==============================================================
Explanation:
For any convex polygon, the sum of the exterior angles is always 360 degrees.
The exterior angles (5x+12), (10x-37) and (9x+1) add to 360. Use this to solve for x.
(5x+12)+(10x-37)+(9x+1) = 360
(5x+10x+9x) + (12-37+1) = 360
24x-24 = 360
24x = 360+24
24x = 384
x = 384/24
x = 16
The expression 10x-37 is then
10x-37 = 10*16-37 = 160-37 = 123
which is the measure of the exterior angle adjacent to angle BCA
The last step is to subtract this from 180 to get angle BCA itself
angle BCA = 180 - 123 = 57
Given:
(7,0), (10,21)
To find the slope of the line that passes through the given points, we use the formula:
where:
m=slope
Based on the given points, we let:
We plug in what we know:
Therefore, the answer is A. The slope is 7.
Step-by-step explanation:
Given
if x = 5 Then
(x+ 3)²
= ( 5 + 3) ²
= 8²
= 64
