Answer:
$276
Step-by-step explanation:
1. Determine 15% of $240
240 x 0.15 = $36
2. Add that number to the original cost
240 + 36 = $276
Not quite sure about the answer...maybe we should look for some better like problems....overall, Good luck. I'm sorry I tried to think the best I can..
Answer:
1 ft
Step-by-step explanation:
From the diagram;
Therefore
Also, AB=8+2=10ft, AD=8ft, AE=4ft. We substitute to get:
Simplify to get:
But AC=AE+EC
This implies that,
5=4+EC
EC=5-1
EC= 1 ft
Tan^2 x + 5tan x + 3 = 0
Let tan x = m, then
m^2 + 5m + 3 = 0
m^2 + 5m + 25/4 = -3 + 25/4 = 13/4
(m + 5/2)^2 = 13/4
m + 5/2 = + or - sqrt(13) / 2
m = (√13 - 5)/2 or (-√13 - 5)/2
tan x = (√13 - 5)/2 or (-√13 - 5)/2
x = arctan((√13 - 5)/2) or arctan((-√13 - 5)/2)
x = 103.0837, 145.1149, 283.0837, 325.1149
