Answer:
B & D
Step-by-step explanation:
both B and D are non linear because they're not lines
Answer: 28.8°
<u>Step-by-step explanation:</u>
∠A = 5(∠B) + 7.2°
∠B = ∠B
Since they are on a straight line, they form a linear pair (sum = 180°)
∠A + ∠B = 180°
Use Substitution:
5(∠B) + 7.2° + ∠B = 180°
Add like terms:
6(∠B) + 7.2° = 180°
Subtract 7.2° from both sides:
6(∠B) = 172.8°
Divide both sides by 6:
∠B = 28.8°
Answer: x = 0
Step-by-step explanation: Multiply to remove the fraction, then set equal to 0 and solve.
Answer:
The base has length 64 m.
Step-by-step explanation:
The area of a triangle = 1/2 * base * height so we have the equation:
256 = 1/2 * b * 8
4b = 256
b = 256/4 = 64 m.
Answer:
No
Step-by-step explanation:
Step 1: Write equation
8u - 1 = 6u
Step 2: Solve for <em>u</em>
- Subtract 6u on both sides: 2u - 1 = 0
- Add 1 to both sides: 2u = 1
- Divide both sides by 2: u = 1/2
∴ u = -1/2 is NOT a solution.
