Ratio of 2 complementary angles = 4:5
Let first angle be 4x
Let second angle be 5x
Sum of two complementary angles = 90
4x + 5x = 90
9x = 90
x = 90/9 = 10
First angle = 4x = 4*10 = 40
Second angle = 5x = 5*10 = 50
I hope it is helpful...
Answer:
9x
9 is the coefficient
Step-by-step explanation:
5x + 4x
These are like terms (they both have the same variable (x))
5x + 4x = 9x
The coefficient is 9, since it's the number in front of a variable.
Hope this helped!
Answer:
360 = x + 30
x = 390 meters
Step-by-step explanation:
Answer: x=3 and y=5
Step-by-step explanation: 11x-6y=3, 5x-8y=-25
11x-6y+6y=3+6y
11x/11=3/11+6y/11
x=3+6y/11
5(3+6y/11)-8y(11)/11
5(6y+3)-88y/11
30y+15-88y/11
88y-30y
58y
11(15-58y)/11=11(-25)
15-58y-15=-275-15
-58y/-58=-290/-58
y=5
x=3+6(5)/11
3+30
33
33/11
x=3
x=3, y=5
