Answer:
x = 7 , y = 7
Step-by-step explanation:
A 45- 45- 90 triangle is an isosceles right triangle with the 2 legs being congruent , that is
x = 7
Using Pythagoras' identity in the right triangle, then
y² = 7² + 7² = 49 + 49 = 98 ( take square root of both sides )
y = 
= 
= 
× = 7
To solve this problem you can do a proportion
to find 'x', we have to cross multiply the numbers.
and
this will get you
to get 'x', we have to divide by 100 on each side
your answer will be
so, Chris must raise 75.25 dollars by himself
It’s A, Because if you do KCF (Keep Change Flip) It would be 1/6 X 7/5.
