Answer:
x=25°, y=10°
Step-by-step explanation:
∠A+∠B=180°
8y+10y=180°
18y=180°
y=10°
∠B+∠C=180°
10y+4x-20°=180°
10*10°+4x=180°+20° (y=10°)
100°+4x=200°
4x=200°-100°
4x=100°
x=25°
Remember that e is equals to 2.717 something and to find the value of the infinities, you must consider there signs. So the e^infinity approaches to infinity while the e^-infinity approaches to zero. I hope you are satisfied with my answer and feel free to ask for more
Answer:
The Circle.
Step-by-step explanation:
The Triangle area is 112 ((14*16)/2), the squares area is 100 (10 * 10) and the circles area is 113.1 (6^2 * pi)
Hope this helps!
Answer:
-3 < x ≤ 8
Step-by-step explanation:
First, write this statement with symbols:
2x - 5 > -3, but also:
2x - 5 ≤ 11
Adding 5 to both sides of the first inequality yields 2x > 2. pr x > 1.
Adding 5 to both sides of the second inequality results in 2x ≤ 16, or x ≤ 8.
Thus, -3 < x ≤ 8 is the shortest way in which to write the given information.
Answer: x=1, y=1, z=-1
Step-by-step explanation:
From the first and 3rd equation, 2x+9y=11.
The first equation is also 4x+16y-4z=24, so add that to the second equation, and you get 6x+27y=33.
Solving, we get x=1 and y=1, meaning that z=-1.
