I think you should do it in a decimal idk if im right but in decimal form it is .1875
Answer:
4.2 ft
Step-by-step explanation:
Reference angle = 77°
Opposite side = DE = x
Hypotenuse = CD = 4.3 ft
Apply the trigonometric function of sine. Thus:
Sin 77 = opp/hyp
Sin 77 = x/4.3
Multiply both sides by 4.3
4.3 × sin 77 = x
x = 4.2 ft (nearest tenth)
It just happens that tan 14 degrees is about 0.25 or 1/4. According to my calculator, it's actaull 0.249.
Now try finding tan 76 degrees to approx. the same level of accuracy.
tan 76 deg = (via calculator) 4.0108. this could be re-written as 4 or 4.1.
Answer:
square root of a number is a value that when multiplied by itself gives the number
