Answer:5
Step-by-step explanation:
2 +3=5
3+2=5
Let 'x' and 'y' be two complementary angles.
The sum of two complementary angles is always 90 degrees.
So,
(equation 1)
It is given that, one angle measures 39 degrees more than 2 times the measure of its complement.
So,
Substituting the value of 'y' from equation 1 in the above equation, we get
So,
Since,
Therefore, the measure of two angles are and .
Answer:
64
Step-by-step explanation:
we have given that mean of 9 students is 84
so total score of 9 students = mean×9
=84×9=756
and we have given mean score of exam is 82 and there is total 10 students so the total score of 10 students =10×82
=820
so the unreadable score = score of 10 students -score of 9 students =820-756=64
<u>(3x³y)(6xy³) </u>= <u>18x^4y^4 </u> = <u>18x^4y^4 </u>= 2x²y²
(-3xy)² (-3xy)(-3xy) 9x²y²
The answer is 1:20. The should leave at 1:20 because 25 minutes to get there plus a 15 minute stop equals 40 minutes. 25 + 15 = 40. So it will take them a total of 40 minutes to get there. If they want to arrive at 2 they have to leave 40 minutes earlier, at 1:20.
