first you have to find the triangle, then you can move to the actual question.
x+30+80 = 180
x+110 = 180
x+110 - 110 = 180-110
x =70
now you can go to the actual question.
y + 70 = 180
y+70- 70 = 180-70
y = 110
there is your answer. hope this is helpful
Answer:
2.5
Step-by-step explanation:
The radius is half of the diameter. 5 / 2 = 2.5
Answer:
Option B. 5.5 ft²
Step-by-step explanation:
Perimeter of the square piece of land = length of fence required
4(length of a side of the square) = 24 ft
Length of a side = 6 ft
Area of the square land = (Side)²
= 6²
= 36 square ft
Area of the side walk = Area of the square - [Area of two triangles separated by the sidewalk]
= 36 - [1/2 (Area Of The Sqaure) + 1/2 (Base) (Height) ]
= 36 - [36/2 + 1/2 (6 - 1) (6 - 1)]
= 36 - (18 + 12.5)
= 36 - 30.5
= 5.5 ft²
Therefore, Option B. is the correct answer.
Answer: d. 2 divided by cot 40 degrees
Step-by-step explanation: in this right triangle, we are given an angle and the adjacent side of the angle. now we have to find for the length of the opposite side. the formula that relates these 3 variables is the tan function which states that:
tan θ = opposite side / adjacent side
where opposite side is the height of the sail
substituting the values into the formula:
tan (40) = height / 2
rearranging in terms of height:
height = 2 * tan (40)
since tan θ = 1 / cot θ, therefore:
height = 2 / cot (40)
