Answer:
x = (9/2)√2 = 4.5√2
Step-by-step explanation:
We know the hypotenuse of an isosceles right triangle is √2 times the length of the side:
9 = x·√2
9√2 = 2x . . . . multiply by √2
(9/2)√2 = x . . . divide by 2
The angle at vertex D is acute.
Triangle DEF is a right traingle.
Answer:
AT = 8
Step-by-step explanation:
Using the sine ratio in the right triangle
and sin45° = 
sin45° = 
= 
= 
Multiply both sides by AT
AT × sin45° = 8, that is
AT × = 8
Multiply both sides by
AT = 8
Answer:
16
Step-by-step explanation:
8/1/2
8 divided by 1/2
