Answer:
Two angles are said to be congruent if their respective sides and angles are of equal measure. Supplementary angles are two angles whose measures sum up to 180°.
Step-by-step explanation:
Answer: 2.1 feet
Step-by-step explanation:
The ladder forms a right angle triangle with the wall and the ground. The length of the ladder represents the hypotenuse of the right angle triangle. The height from the top of the ladder to the base of the wall represents the opposite side of the right angle triangle.
The distance, d from the bottom of the ladder to the base of the wall represents the adjacent side of the right angle triangle.
To determine the distance, d from the bottom of the ladder to the base of the wall, we would apply we would apply the cosine trigonometric ratio.
Cos θ = adjacent side/hypotenuse. Therefore,
Cos 65 = d/5
d = 5Cos 65 = 5 × 0.4226
d = 2.1 feet
Perfect pizza because 15*6=90, and of each pizza place were to make 90 pizzas, perfect pizza uses 60 cups of cheese while pizza express only uses 36. The difference is by 24 cups.
Answer:
If 
we get 
which is true. so we have a first set of solutions given by
;
Else, if 
we can divide both sides by it and we get
Which gives us a second set of solutions given by 
;
We can group all solutions (doesn't matter, but it's more elegant!) by writing
