Answer:
Hey there!
The equation would be y=-1/2x-3.5
Hope this helps :)
Answer:
159
Step-by-step explanation:
Based on process of elimination, it cant be 51 nor 55 because that angle is 100% bigger than 90 degrees. To find it correctly, all you would do is add them. 105 + 54= 159

Answer:
2 1/2 feet
Step-by-step explanation:
The Pythagorean theorem is not useful in this problem.
__
If you reflect the triangle over the vertical line, you find that line to be the altitude of an equilateral triangle. That is, all of the vertex angles are 60°.
The base of that equilateral triangle is necessarily twice the length of the base of the triangle shown. All sides of the equilateral triangle are the same length, so all are 5 ft. The base of the triangle shown is half that.
The base (short leg) of the triangle shown is 2 1/2 feet.
_____
Since angles are given, this can be solved using trigonometry. The short leg will be (5 ft)·cos(60°) = (5 ft)(0.5) = 2.5 ft. (The cosine of 60° is one of the few exact rational values of trig functions of exact angles measured in degrees.)
Answer:
No
Step-by-step explanation:
You are given three pairs of angle ≅. You can not prove Δ≅Δ by AAA.
you do not have a side that you know are ≅.
The ASA means Angle - Side - Angles
