Answer:
A
Step-by-step explanation:
All triangles have 180 degrees, these set of measures do not add up to 180°. They add up to 181°, so it is the answer.
Answer:
5:3
Step-by-step explanation:
to find the scale factor you set up the proportion as 15/9 and reduce to 5/3
Using the points (0,14) and (10,0), the gradient of the line is (14-0)/(0-5) which simplifies to -7/5.
From these points, we can also see that when the x value is zero, the y value is 14. Therefore the y-intercept is 14.
We can then put this into the equation of a straight line, y=mx+c:
y = (-7/5)x + 14
