Answer:
The angle z is 130 degrees.
Step-by-step explanation:
A straight line is 180 degrees.
Now think about how that line looks, you cut 50 degrees off of the whole 180.
So the equation is 180-50=z
z=130
I hope I have been of assistance to you, have a good day.
Answer:
Step-by-step explanation:
Use FOIL method
(x + 6)(x +6) = x*x + x*6 +6*x + 6*6
= x² +<u> 6x + 6x</u> + 36 {add like terms}
= x² + 12x + 36
Because x is not defined, it is assumed to be the height of the balloon.
Note that
75° 20' = 75.333°
49° 30' = 49.5°
From the figure shown below, obtain by definition,
a = x cot 49.5° = 0.8541x
b = x cot 75.333° = 0.2617x
Because a + b = 400 ft, therefore
0.8541x + 0.2617x = 400
1.1158x = 400
x = 358.49 ft
Answer: 358 ft (nearest whole number)
