Chee is flying a kite, holding her hands a distance of 3.25 feet above the ground and
Mademuasel [1]

The height of the kite above the ground is 58.68 ft

Let x be the height of the kite above Chee's hand.

The height of the kite above Chee's hand, the string and the horizontal distance between Chee and the kite form a right angled triangle with hypotenuse side, the length of the string and opposite side the height of the kite above Chee's hand.

Since we have the angle of elevation from her hand to the kite is 29°, and the length of the string is 100 ft.

From trigonometric ratios, we have

tan29° = x/100

So, x = 100tan29°

x = 100 × 0.5543

x = 55.43 ft.

Since Chee's hand is y = 3.25 ft above the ground, the height of the kite above the ground, L = x + y

= 55.43 ft + 3.25 ft

= 58.68 ft to the nearest hundredth of a foot

So, the height of the kite above the ground is 58.68 ft

andre [41]

Answer:

A)  T=\frac{-20}{4}

B) T = -5 °C

Step-by-step explanation:

A) Let T be the change in temperature of the week. T is determined as the total temperature change (-20°C) divided by the number of weeks that have passed (4 weeks). The expression is:

T=\frac{-20}{4}

B) In order to simplify the expression, simply perform the division.

T=\frac{-20}{4}\\T=-5^oC

This means that the temperature has dropped by 5 degrees each week.
