Hello :
f(x) = √(x-3)
answer: B x-3 <span>≥ 0</span>
Lets x = missing angle
x = 180 - (60+80)
x = 180 - 140
x = 40
answer
40
Answer:
32/27 or 1/5/27 or a repeating decimal 1.185
Step-by-step explanation:
Use the Pythagorean theorem
<span>the hypotenuse is the ladder which is 20 ft and the base is 12 ft thus </span>
<span>a^2 + b^2 = c^2 </span>
<span>a^2 + 144 = 400 </span>
<span>a^2 = 256 </span>
<span>a = 16 </span>
<span>so its 16 ft</span><span />
