A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you use three numbers and get four facts. For example, you canform a fact family using the threenumbers 10, 2, and 12: 10 + 2 = 12, 2 + 10 = 12, 12 − 10 = 2, and 12 − 2 = 10.
Answer:
456
Step-by-step explanation:
Answer:
x = 437.3 ft
Step-by-step explanation:
Angle of elevation = angle of depression = 29°
Reference angle = 29°
Adjacent side = x
Hypotenuse = 500
Applying trigonometric ratio, we have:
Cos 29 = x/500
Multiply both sides by 500
500*cos 29 = x
437.309854 = x
x = 437.3 ft (nearest tenth)
