Answer:
125
Step-by-step explanation:
( 3x - 70 ) is exterior angle.
60 and x are interior angles.
Formula : -
Exterior angle of a triangle
= Sum of two interior angles in a triangle
3x - 70 = x + 60
3x - x = 60 + 70
2x = 130
x = 130 / 2
x = 65
m∠LKM = 3x - 70
= 3 ( 65 ) - 70
= 195 - 70
m∠LKM = 125
Answer:
The actual length of the helicopter is <u>23 feet</u>.
Step-by-step explanation:
Given:
On a scale drawing, a helicopter is 2.3 feet long.
The scale on the drawing shows a ratio of 1 foot to 10 feet.
Now, to find the actual length of the helicopter.
Let the actual length of helicopter be
.
On scale drawing length of helicopter = 2.3 feet.
The scale on the drawing shows a ratio = 1:10.
Now, as ratios are given so by setting proportion we solve it:

<em>By cross multiplying we get:</em>
⇒ 
⇒ 
⇒ 
Therefore, the actual length of the helicopter is 23 feet.
