Answer: 110
Step-by-step explanation:
1.4 x 10 = 14
That's your answer.
0.4 and 0.40 are equal. That zero on the hundredths place does not matter.
The answer is C. Note that angle C is 180-90-45=45 degrees, so this is a你isosceles right triangle, and it helps if we draw it on a piece of paper. Since angle B =angle C, AB must be equal to AC=4, and BC=4*\sqrt(2), according to the Pythagorean Theorem.
