An isosceles triangle has two angles measuring 54.5 and 71.
What is the measure of the
third angle?

x=54.5

Step-by-step explanation:

54.5+71+x=180

125.5+x=180

x=54.5

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
