Answer:
≈ 35.91
Step-by-step explanation:
The law of sines lets you find the other sides:
DN/sin(M) = MN/sin(D) = DM/sin(N)
Angle D is 180° -75° -45° = 60°, so the remaining sides are ...
DN = sin(M)/sin(N)×DM = sin(75°)/sin(45°)×10 ≈ 13.66
MN = sin(D)/sin(N)×DM = sin(60°)/sin(45°)×10 ≈ 12.25
The perimeter is the sum of the side lengths, so is ...
10 + 13.66 +12.25 = 35.91
Answer:
X= 23 degrees
Step-by-step explanation:
117 degrees minus 94 equals x

Answer:
![x = - 3](https://tex.z-dn.net/?f=x%20%3D%20%20-%203)
![y = 1](https://tex.z-dn.net/?f=y%20%3D%201)
Step-by-step explanation:
Write the system
![3x - y = - 10](https://tex.z-dn.net/?f=3x%20-%20y%20%3D%20%20-%2010)
![x + y = - 2](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%20%20-%202)
Solve by Elimination.
multiply the second equation by -3.
![3x - y = - 10](https://tex.z-dn.net/?f=3x%20-%20y%20%3D%20%20-%2010)
![-3x - 3y = 6](https://tex.z-dn.net/?f=%20-3x%20%20%20-%203y%20%3D%20%206)
Add the Equations.
![- 4y = - 4](https://tex.z-dn.net/?f=%20-%204y%20%3D%20%20-%204)
![y = 1](https://tex.z-dn.net/?f=y%20%3D%201)
Plug this back in one of the equations.
![x + 1 = - 2](https://tex.z-dn.net/?f=x%20%2B%201%20%3D%20%20-%202)
![x = - 3](https://tex.z-dn.net/?f=x%20%3D%20%20-%203)
Answer: C
Step-by-step explanation:
Standard form for multi-variable expession( quadratic, trinomial, polynomial, etc) are represented by something like this.
ax^2+ bx+c, which means the stating term is the degree or exponet with the highest number then as we go right the degree go smaller.
So that means 5x^4 will be the starting term so a and b are ruled out. The next term will be x squared o x^2 so the only answer that has it second is C
