Answer:
23
Step-by-step explanation:
h(a) = 5x-2
h(5) = 5(5)-2
h(5) = 25-2
h(5) = 23
Plug in 5 as x
h(x) = 5x - 2
h(5) = 5(5) - 2
h(5) = 25 - 2
So, h(5) = 23
y + 3 +24 = 237
y + 27 = 237
y + 27 - 27 = 237 -27
y = 210

Supplementary means that the angles have to add up to 180, so you have your equation.
180=5x+17x-18
198=22x
x=9
Then to find the measures of the angles, you plug x back in.
m∠ABD=5(9)=45 degrees
m∠BDE=17(9)-18=153-18=135 degrees
