Step-by-step explanation: Did a quiz with the same question.
The number of blue roses will be 72. Then the number of red roses that she have at first is 84.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Mrs Fernandez has a total of 156 red and blue roses.
After selling the same number of red and blue roses.
She had 1/3 of the number of red roses and 2/9 of the number of blue roses left.
Let x be the number of red rose and y be the number of blue roses.
Then the equation will be
x + y = 156 ...1
2x/3 = 7y/9
6x = 7y ...2
By solving the equations 1 and 2, we have
x = 84 and y = 72
Then the number of red roses that she have at first is 84.

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
