The hypotenuse is 20 ft
Step-by-step explanation:
- Step 1: This is a right triangle, so the trigonometric ratio cosine can be used to find the length of the hypotenuse. Given side opposite to ∠B, AC = 18 ft and ∠A = 40°,
cos 40° = adjacent side/hypotenuse = AC/AB = 18/AB
⇒ AB = 18/cos 40° = 18/0.76 = 23.5 ft ≈ 20 ft
Answer:
7 cuts
Step-by-step explanation:
A net of a cube looks like the image below.
It has 5 edges connected to each other; two to the side, three in the middle.
That means that 12 - 5 = 7 cuts have to be made.
Answer:
86,400
Step-by-step explanation:
To simplify the expression, we distribute terms accordingly. It is done as follows:
<span>(3a – 4b)(a + b)
3a</span>² + 3ab -4ab -4b²
3a² - ab -4b²
Therefore, the correct answer is option A, <span>3a^2– ab – 4b^2.

When you have
you can solve the equation by multiplying both sides by 1/4. Then simplify.
