Pythagorean theorem: a^2 + b^2 = c^2
36^2 + b^2 = 85^2
1296 + b^2 = 7225
b^2 = 7225 - 1296
b^2 = 5926
b = square root of 5929
b = 77 inches long
Answer:
The first question tan(24) = x/12 because tan(x) = opposite/adjacent
so x in radians ≈ -25.618....
x in degrees ≈ 5.342....
For the second question tan(72) = x/20
x in radians ≈ -5.248....
x in degrees ≈ 61.553....
Answer: You would have 50 quarters and 20 dimes
Step-by-step explanation: 50-30=20 so, 20+50=70
Evaluate the given function at x=1:

<span><span>f<span>(1)</span></span>=0+2</span>
<span><span>f<span>(1)</span></span>=<span>2</span></span>
<span><span>THIRD ONE</span></span>
Answer:
y=6
Step-by-step explanation:
-6y+15=-21
-6y=-21-15 (it becomes negative on this side.)
-6y=-36 (divide both sides by -6.)
y=6
