Ok, to prove the two triangles, we need reasoning:
1) the side AC is common (as you can see, both triangles share the side AC)
2) angle DCA is equal to angle BAC (this is due to alternate angles)
3) angle BCA is equal to angle DA (again, this is due to alternate angles)
Answer:
$44.40
Step-by-step explanation:
Markup is the difference between the sell price and the cost of building
1) Find total cost of building the lawn mower: $35 + $39.17 + $36.43 = $110.6
2) Subtract the total cost from the sell price: $155.00 - $110.6 = $44.40
If you're looking for the whole angle i'm pretty sure it's 74 degrees. If you're solving for x, x=8
T=32+0.33c
b.t=32+0.33c
t=32+0.33(10)
t=32+(3.30)
t=35.30
