Answer
Find out the altitude of the equilateral triangle .
To proof
By using the trignometric identity.
As shown in the diagram
and putting the values of the angles , base and perpendicular
solving
As
put in the above
a = 4 × 3
a = 12 units
The length of the altitude of the equilateral triangle is 12 units .
Option (F) is correct .
Hence proved
Answer:
198 degrees
Step-by-step explanation:
Such a shape is called a 20-gon, such shapes have an interior angle of 162. Hence, the exterior angle = 360 (Complete angle) - 162 (The interior anlge) = 198 degrees, Hope my answer helps you, Thank you, and please add me as brainliest! Thanks
Answer:
huh?
Step-by-step explanation:
.............................
( 4,20)is the correct answer
You need to isolate x.
71 - 5x = 9x - 13
Add 13 to both sides.
84 - 5x = 9x
Add 5x to both sides.
84 = 14x
Divide both sides by 14.
6 = x
<h3>The answer is x = 6.</h3>
