Answer:
(-4,5)
Step-by-step explanation:
-X and X cancel each other out so your're left with
Y=9
2Y=6
Add the like terms together to get 3Y=15
so Y=5.
Then plug in y into one of the equations to get x.
-x+5=9
-x=4
X=-4
So the solution is (-4,5)
Answer:
The answer to your question is 14° and 76°
Step-by-step explanation:
Data
leg 1 = x
leg 2 = x/4
angle 1 = ?
angle 2 = ?
Process
To solve problem use trigonometric functions. We must use the trigonometric function that relates both legs (tangent).
tangent Ф = Opposite side / Adjacent side
-Substitution
tan Ф = (x/4) / x
-Simplification
tan Ф = x / 4x
tan Ф = 1/4
- Find Ф
Ф = tan⁻¹(1/4) = 14°
- Find the other acute angle
The sum of the internal angles in a triangles equals 180°
Ф + Ф₁ + 90° = 180
-Solve for Ф₁
Ф₁ = 180 - 90 - 14
-Result
Ф₁ = 76°
Answer:
4 - (3 - 5) = <em>6.</em>
