Answer:
33°, 57°
Step-by-step explanation:
The sum of angle measures is 90°, so we can write ...
(x +3) + (2x -3) = 90
3x = 90 . . . . . . . . . . . . simplify
x = 30 . . . . . . . . . . . . . divide by 3
The first angle is 30+3 = 33 degrees.
The second angle is 2·30-3 = 57 degrees.

Check:
33° +57° = 90°
Answer: -4x^8/y3
Step-by-step explanation:just simplify it
I DONT KNOW I REALLY WISH I COULD HELP
Answer:
6
Step-by-step explanation:
The ratio of boys to girls is 2:5
let the number of boys be 2x -------(i)
and number of girls be 5x
and the total number of students is 21
therefore we know that..
2x+5x = 21
on solving for x,
7x=21
x= 21/7
x=3
now, by putting the value of x in (i),
2x = 2×3 = 6
therefore, there are 6 boys in the classroom.
you find the no. of girls similarly.
hope it helps !!...
PLEASE MARK BRAINLIEST ♡
She made the mistake in step 4
She should have divided by -2 not just 2 alone
