It would be a 90%. In the calculator 18 is what percent of 20.
Answer:
Step-by-step explanation:
<u>Given inequality:</u>
<u>Since b is negative, when multiplied by b, the inequality changes to opposite direction:</u>
true because if you add up 4 90°you get 360
Answer:
area = 2604 in²
Step-by-step explanation:
area = L x W
area = 42 x 62 = 2604 in²
Answer:
a = √11 and b = 6
Step-by-step explanation:
Refer to attached picture for reference
for an right triangle with angle θ
we are given
cos θ = 5/6 = length of adjacent side / length of hypotenuse
hence
adjacent length = 5 units
hypotenuse length = 6 units
the missing side is the "opposite" length which we can find with the Pythagorean equation. in our case:
hypotenuse ² = adjacent ² + opposite² (rearrange)
opposite ² = hypotenuse ² - adjacent ²
opposite ² = 6² - 5²
opposite = √ (6²-5²) = √11
sin θ = opposite length / hypotenuse (substitute values above)
sin θ = √11 / 6
hence a = √11 and b = 6
