Answer:
h = 18( I might be wrong though)
Step-by-step explanation:
If BE and ED are perpendicular, that means this angle is supplementary.
BEF = 3h-12
FED = 2h - 23
BEF + FED = 90
3h-12 + 2h - 23 = 90
5h - 35 = 90
5h = 90
h = 18 degrees
Answer:
let the total number of students bex
Then
10%of x=1120
or,(10/100)x=1120
or,x/10=1120
or,x=11200
The total no. of students is 111200
There is no solution. 2(x-1)^2 = 3-5 (x-1)^2 = -1 you will get an imaginary solution
Download photomath it’s really helpful for question like that it also explains it :)
