Answer:
x = y = (√10)/2
Step-by-step explanation:
In an isosceles right triangle, the side lengths are equal, and they are equal to (√2)/2 times the hypotenuse length.
x = y = (√5)(√2)/2
x = y = (√10)/2
Answer:
x = y =

Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = 
sin45° =
=
=
( cross- multiply )
2x =
( divide both sides by 2 )
x =

Since the base angles are 45° then the triangle is isosceles with both legs congruent , thus
x = y =

5.5 + 2.1x + 3.8x - 4.1
5.5-4.1 +x(2.1+3.8)
1.4 +x(5.9)
5.9x+1.4
these are equivalent if there is a plus sign between 1.4 5.9x
