None of those could be a radical, you would have to have a radical symbol for it to become a radical
Answer:
Step-by-step explanation:
45=32+13
tan 45=tan(32+13)
or 1-tan 32 tan 13-tan 32-tan 13=0
<h2>

Step-by-step explanation:
Obtuse: An obtuse angle is an angle more than 
but less than 
.
Example : 
,
etc.
Acute : An acute angle is an angle less than
Example : 
,
etc.
Straight : A straight angle is .
Right: A right angle is .
Since the angle is more than but less than . So, it is an obtuse angle.
Answer:
$26.88
Step-by-step explanation:
Cost of a ply wood = $0.56 per square foot
If Dakota wants to build 8 birdhouses and he needs to paint 6 square feet of plywood for each birdhouse, then the total area fir the 8 bird house will be expressed as:
8 * 6
= 48 sq. feet
Hence the area of 8 bird houses is 46sq. feet
Next is to calculate the amount it will cost to make the 8 bird houses.
Since 1 sq. foot = $0.56
48 sq. feet = y
cross multiply
y * 1 = 48 * 0.56
y = 26.88
Hence it will cost Dakota $26.88 to make hid bird houses
Answer: −5
Step-by-step explanation:
simplify: (−5)
Re-order terms so constants are on the left:
(−5)f(−5)−5
