Answer: B = 56 degrees
Step-by-step explanation: Complementary angles add up 90 degrees. So we will set both of the equations equal to 90 degrees and then solve from there.
6x+8+5x+21=90
1. Simplify 5x + 6x and 21 - 8
11x+13=90
2. Subtract 13 from both sides.
11x=90-13
3. Simplify 90-13 to 77.
11x=77
4. Divide both sides by 11.
x = 77/11
5. Simplify 77/11 to 7
x=7
Now we have to take the value of x and substitute it back into B = (5x+21)
1. Substitute
B = (5(7)+21)
B = 35 +21
B = 56

Answer: 3
Step-by-step explanation:
In 5 years, Jumoke will be 16. 16 divided by 2 is 8. Amina will be 8 in 5 years. If we subtract 5 from 8, we see that Amina is 3 currently.
90 degree rotation clockwise : (a,b) --> (b,-a)
so... (24,-15) --> (-15,-24) is a 90 degree clockwise rotation
I don’t know this answer but I think it’s 81
Answer:
The answer is
One: 28, 29, 30
Two: 75,77
Step-by-step explanation:
One
Let the three numbers be (x - 1) , x , and x + 1
(x - 1) + x + (x +1 ) - 12 = 75 Remove the brackets
x - 1 + x + x + 1 - 12 = 75 Combine the like terms on the left
3x - 12 = 75 Add 12 to both sides
3x = 75 + 12
3x = 87 Divide by 3
x = 87/3
x = 29
Two
Let the first odd number = 2x -1
Let the second odd number = 2x + 1
2x - 1 + 2x + 1 + 18 = 170 Combine like terms on the left.
4x + 18 = 170 Subtract 18 from both sides.
4x = 170 - 18 Combine like terms on the right
4x = 152 Divide by 4
4x/4 = 152/4
x = 38
2 * 38 - 1 = 75
2 * 38 + 1 = 77
