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
Answer:
44cm^2
Step-by-step explanation:
We work with area for rectangles using the face of the longer length first as this is the awkward length the perpendicular side to the easy calculation of the square and sits perpendicular to the square.
We choose the longer length and plug in and choose one of the two calculation answers.
11 x 4 = 44
11 x 6 = 66
We see the answer is 44cm^2, so we choose this one.
