Answer:
C. m<1 + m<5 = 180 (reason: they are consecutive angles, and should be congruent)
This is a question that will require Pythagoras' theorem as you want to find the length of a diagonal of a triangle and are given the measurements of two sides. I have attached a picture of how to solve this problem.
To the nearest 10th of a foot, the answer is 77.6ft
5 using the Pythagorean theory
Answer:
<em>x - 5y = - 10 </em>
Step-by-step explanation:
y = mx + b (b is y-intercept)
m =
~~~~~~~~~~~~
x + 4y = 8 ⇔ y =
x + 2 ⇒ y-intercept is 2 and coordinates of y-intercept are <u><em>(0, 2)</em></u>
(5, 3)
m =
=
y =
x + 2 (slope-intercept form)
<em>x - 5y = - 10</em> (standard form)
