Answer:
m<X = 
Step-by-step explanation:
From the given isosceles triangle, we have;
<W and <V as the base angles
So that,
m<W = m<V = 27 (base angles of an isosceles triangle are equal)
Thus,
m<X + m<V + m<W = 180 (sum of angles in a triangle)
m<X + 27 + 27 = 180
m<X + 54 = 180
m<X = 180 - 54
= 126
m<X = 
Answer:
medium
Step-by-step explanation:
The right answer is Medium, because to travel through the ear the sound wave must go through the ear drum.
The given ratio of the sides of the triangles is 4:10:7. Let the sides be 4x, 10x and 7x .
And given perimeter is 252 meters .
Perimeter is the sum of all sides. So we get

Dividing both sides by 21

So the sides are

The answer is k is greater than or equal to 18
