Answer:

We also know that If two angles are complementary then their sum is equal to 90°. So, two angles ∠1 & ∠2 are complementary.

Step-by-step explanation:

As BA is perpendicular to BC. So, angle ∠ABC is 90°.

We also know that If two angles are complementary then their sum is equal to 90°. As ∠ABC is the sum of the ∠1 & ∠2. In other words, ∠1 & ∠2 are complementary. So, two angles ∠1 & ∠2 are complementary.

Lets prove this.

Given: BA ⊥ BC

Prove: ∠1 & ∠2 are complementary.

Statement Reasons

1. ∠1 & ∠2 are complementary 1. Given

2. ∠1 + ∠2 = 90° 2. Def. of complementary angles

Approximately how much higher up the wall does the ladder in Figure 2 rest compared to the ladder in Figure 1?

katovenus [111]

Answer:

Answer B, 3 feet

Step-by-step explanation:

For the first ladder, the height of the ladder up the ladder can be found with the formula $\sqrt{10^2-8^2}=6$ . For the second ladder, you can use the same formula to find that the ladder is $\sqrt{10^2-4^2}\approx 9$ . 9-6=3, and therefore the correct answer choice is B.

Sydney says that 4/8 is closer to 0 than 1 is she correct explain

Alla [95]

Sydney is wrong. $\frac{4}{8}$ is equivalent to the fraction $\frac{1}{2}$ , which is the same as 0.5 in decimal form. It is not closer to either 0 or 1 as the distance between the two numbers are equal. (0.5 - 0.5 = 0, 0.5 + 0.5 = 1. It is exactly in the middle of 0 and 1.
