Answer:
30 degree
Step-by-step explanation:
x + x + 60 + 60 = 180 degree (being sum of interior angles of a triangle )
2x 120 = 180
2x = 180 - 120
x = 60/2
x = 30 degree
h(x) = kx - 32
h(x) = 40
40 = kx-32
kx = 72
x = 72/k
Minus lw froom both sides
S-lw=wh+hl
S-lw=h(w+l)
divide both sides by (w+l)
![\frac{S-lw}{w+l}](https://tex.z-dn.net/?f=%20%5Cfrac%7BS-lw%7D%7Bw%2Bl%7D%20)
