How come it’s a right triangle, I think you do a2+b2=C2. Therefore, you do 9.4 times 9.4 and then 15.1 times 15.1. So it will be 9.4 + b2=15.1. 88.36+ b2=228.01. Then you subtract that and it will be 139.65. Then you do square roots because you are trying to get rid of the second power. And the final answer is 11.81736011. How they told you to round it to the nearest tenth, I will be 11.8. I think this is the answer.
Answer:
120 m
Step-by-step explanation:
Let the length of the pole be a and the shadow be b at 58° and b+90 at 36°.
<u>Then, as the pole and its shadow form a right triangle, we have:</u>
<u>As,</u>
- tan (58°) ≈ 1.6
- tan (36°) ≈ 0.727
<u>The equations change to:</u>
<u>Comparing the two equations:</u>
- 1.6b = 0.727b + 0.727*90
- 1.6b - 0.727b = 65.43
- 0.873b = 65.43
- b = 65.43/0.873
- b ≈ 75
<u>Then </u>
- a = 1.6b = 1.6*75 = 120 m
Answer:
Area of the doormat is <u>0.45 square yards</u>.
Step-by-step explanation:
Given:
The dimensions of a rectangular doormat are 0.6 yard and 75% of a yard.
Now, to find the area in square yards of the door mat.
75% of a yard.
75% of 1 yard.
The dimensions are 0.6 yard and 0.75 yard.
Now, to get the area of doormat:
Therefore, area of the doormat is 0.45 square yards.
I just answered this question(s). mean is average. So you just add all the numbers up per country and divide by how many numbers there are. I hope you know how to graph otherwise look it up on kan academy and the country with the lowest number for height is the gold medalist. And the top three fastest go as gold, silver and bronze<<<<in this specific order.
Answer:
Option (D)
Step-by-step explanation:
By applying Sine rule in the right ΔABD,
Sin(A) =
Sin(60)° =
BD =
=
Now by applying Cosine rule in the right ΔBDC,
Cos(45)° =
x =
x =
Therefore, Option (D) is the correct option.
