Answer:
I think the author is meaning to tell you to use your imagination to think about what will happen when you enter. You don’t know until you through it.
Step-by-step explanation:
The relation between the two angles ∠a and ∠b is that they are complementary angles. The correct option is B.
<h3>What are complementary angles?</h3>
The angles when added give the sum of 90 degrees and are called complementary angles. The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
In the given figure it is observed that the two angles ∠a and ∠b when added give 90 degrees.
Therefore, the relation between the two angles ∠a and ∠b is that they are complementary angles. The correct option is B.

Step-by-step explanation:
<u>Step 1: Define</u>
2(k - 5) + 3k = k + 6
<u>Step 2: Solve for </u><em><u>k</u></em>
- Distribute 2: 2k - 10 + 3k = k + 6
- Combine like terms: 5k - 10 = k + 6
- Subtract <em>k</em> on both sides: 4k - 10 = 6
- Add 10 on both sides: 4k = 16
- Divide 4 on both sides: k = 4
<u>Step 3: Check</u>
<em>Plug in k into the original equation to verify it's a solution.</em>
- Substitute in <em>k</em>: 2(4 - 5) + 3(4) = 4 + 6
- (Parenthesis) Subtract: 2(-1) + 3(4) = 4 + 6
- Multiply: -2 + 12 = 4 + 6
- Add: 10 = 10
Here we see that 10 does indeed equal 10.
∴ k = 4 is the solution to the equation.
