Answer: The value of x in a triangle is 120°
Step-by-step explanation:
Answer:
x = 24
Step-by-step explanation:
A 45- 45- 90 triangle is isosceles ( base angles congruent )
The the legs are congruent , both 12[tex]\sqrt{2}[/tex]
Using Pythagoras' identity in the right triangle , then
x² = (12[tex]\sqrt{2}[/tex] )² + (12[tex]\sqrt{2}[/tex] )² = 288 + 288 = 576 ( take square root of both sides )
x = [tex]\sqrt{576}[/tex] = 24
