Answer:
13
Step-by-step explanation:
Multiply 16 by 12 = 192
Add 3 = 195
80% Of 195 = 156
156 / 12 = 13
13 feet
Subtract 3 from each side:
3x = -30
Divide each side by 3 :
x = -10
Answer:
x = 9.367
Step-by-step explanation:
we have to use the sin formula so its
Sin = opp / hypotenuse
sin 42 = x / 14 <u>Multiply 14 from both side</u>
x = 14 sin 42
x = 9.367
The answer would be √32 or 4√2 (which is simplified) because of pythagoras' theorem. If we substitute a = b = 4 into it, then c must equal the root of 16 + 16, or 32.
