Supplementary angles are those whose sum is equal to 180° while those that are complementary are those whose sum is equal to 90°. Since, we are given that bre is the complement of itself, its measure can be calculated through the equation,
m∠bre + m∠bre = 90°
m∠bre = 45°
Then, for the relationship of bre and tap, we have the equation,
m∠bre + m∠tap = 180°
45° + m∠tap = 180°
m∠tap = 135°
The measure of tap is equal to 135°.

Determine the probability of red then blue jelly? i.e. P(R and B)
From the question, we understand that the red jelly bean was not replaced. This means that the number of jelly beans reduced by 1 after the picking of the red jelly bean
So, we have:
This is then solved further as:
The probability has a denominator of Total - 1 because the number of jelly beans reduced by 1 after the picking of the red jelly bean
The equation becomes:
Answer:
They need to find 360 students in total
Step-by-step explanation:
The total amount for fees comes out to be 300$.
To make a profit of 1500, you have to add 1500$ to 300$, since 300 is the cost of the dance.
After adding this together, you get a cost of 1800$.
Divide this amount by the cost of each ticket, which is $5.
Your result is 360; you need 360 students to cover the cost and have a net profit of 1500$
Answer:
$2,000 or 6.25%
Step-by-step explanation:
1000 x 2 = 2000
28000 + 2000 = 30000 Juan's salary after 2 years
500 x 2 = 1000
31000 + 1000 = 32000 Mariana's salary after 2 years
30000 - 32000 = 2000 difference in salary
2000/32000 x 100= 6.25 difference in salary in percentage
