Answer: 111.4m
Explanation:
1) Trigonometric ratios
You only need to use tangent ratio.
tangent ratio = opposite-leg / adjacent-leg = balloon height / horizontal distance
2) First, find the height of the ballon when he is watching at an angle of elevation of 28°
tangent ratio = opposite-leg / adjacent-leg = balloon height / horizontal distance
tan(28°) = balloon height/65m ⇒balloon height = tan(28°)×65m
balloon height = 34.56m
3) Second, find the height of the balloon,when he is watching at an angle of elevation of 66°
tan(66°) = height of the balloon / 65m ⇒ height of the balloon = tan(66°)×65m
height of the balloon = 145.99m
4) Vertical distance the balloon ascended while Charlie watched.
Subtract the final initial height from the final height:
145.99m - 34.56m = 111.43m
4) Round to the nearest tenth: 111.4 m
Answer:
13 because all you need to do is multiply 10 by 3 then subtract 27
Answer:
I will be needing a picture for this question. However, here is a formula to help you out! y2-y1/x2-x1 (the Xs are on the bottom, and the Ys are on the top. Pick an 2 ordered pairs, and then put them like the formula. X2 and Y2 are an ordered pair, same for X1 and Y1.) Hope this helped ;)
Step-by-step explanation:
Answer:
x-intercept = (-8, 0)
y-intercept = (0, -2)
Step-by-step explanation:
Given linear equation is: x + 4y = - 8
For x - intercept: Plug y = 0 in the above equation.
For y - intercept: Plug x = 0 in the given linear equation.
4 is the least the amount of sides the polygon can have
