That would be D.
The 2 triangles CAB and ADC are right-angled ( given).
The hypotenuse AC is common to both triangles.
The 2 legs AB and DC are congruent (given).
So they are congruent By HL.
Answer:
x=-0.5 or x=-1/2
Step-by-step explanation:
To do this without a calculator, the best method would be chunking.
Minus 36 from 936 in groups of ten until a smaller number is reached; record the number in each group.
936 - (10 x 36)
936 - 360 = 576
576 - (10 x 36)
576 - 360 = 216
216 - (5 x 36)
216 - 180 = 36
36 - (1 x 36)
36 - 36 = 0
Add up all the bold numbers
10 + 10 + 5 + 1 = 26
96 cubes. If the 8 ft container was vertically standing and the cubes would be filed in a single stack.

An example should help :-
Simplify sqrt 20:-
sqrt 20 = sqrt (4 * 5) = sqrt 4 * sqrt5 = 2 sqrt5
cube root of 54 = cube root 27 * cube root 2 = 3 cube root 2
The rule is to factor the number and look for perfect squares or cubes, etc.
