Step-by-step explanation:
i assume that's your question?
First let’s write down what 2 fourth would look like. It would look like 2/4 (on the computer/phone it looks a little different, if you were to write it out the 2 would be over the 4). Now think is there anything that 2 and 4 can both be divided by. The answer is yes! They can both be divided by 2. So divide them both by 2. 2 divided by 2 is 1, and 4 divided by 2 is 2. So your answer becomes 1/2, or one half. There is nothing else they can both be divided by so that’s your final answer.
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
