Zamir needs to determine the height of the building

Svetach [21]

Answer:

Height of the building = 115.4 ft.

Step-by-step explanation:

Height of building = AB + 46.4 + CD + 30.5

By applying Pythagoras theorem in ΔABP,

(26)² = (10)²+ (AB)²

676 - 100 = AB²

AB² = 576

AB = 24 ft

By applying sine rule in ΔCDE,

cos(60°) = $\frac{CD}{CE}$

CD = CE × $\frac{1}{2}$

CD = $\frac{29}{2}$

CD = 14.5 ft

Total Height = 24 + 46.4 + 14.5 + 30.5

= 115.4 ft

Basit played and online Pin Ball game the first time we got our score of 25000 point then he is called 125000 point and third ti

Marianna [84]

Answer:

Average score per game = 60,000 per game

Step-by-step explanation:

Given:

Points scored in first game = 25,000

Points scored in second game = 125,000

Points scored in third game = 30,000

Find:

Average score per game

Computation:

Average = Sum of observation / Number of observation

So,

Sum of all game = 25,000 + 125,000 + 30,000

Sum of all game = 180,000

Number of games = 3

Average score per game = 180,000 / 3

Average score per game = 60,000 per game
