Answer:
x=97
Step-by-step explanation:
first find the angle measure to the right of 139
180-139=41
the sum of a triangles angles must be 180
so 180-42-41=x
x=97
The speed of the airplane is 360 km/h while the speed of the wind is 40 km/h.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let a represent the speed of the airplane and b represent the speed of the wind, hence:
(a + b)6 = 2400
a + b = 400 (1)
Also:
(a - b)7.5 = 2400
a - b = 320 (2)
From eqn 1 and 2:
a = 360 km/h, b = 40 km/h
The speed of the airplane is 360 km/h while the speed of the wind is 40 km/h.
