Answer:
The angle of elevation from the base to the top of the mountain is 30°.
Step-by-step explanation:
Given: Vertical height of mountain is 650 feet and the distance from the top of the mountain to the base is 1300 feet.
To find: The angle of elevation from the base to the top of the mountain.
Let AB be the height of mountain and BC be the base.
Then, according to question, AB=650 feet and AC=1300 feet.
Let ∠ACB=.
Then, in ΔABC,
⇒
⇒
⇒°
Hence, the angle of elevation from the base to the top of the mountain is 30°.
Answer:
Not sure if this is correct but...
Perimeter= 3x+2+3x+2+2x-1+2x-1= 10x+2
Area= (3x+2)(2x-1) = 6x^2 +x-2
Step-by-step explanation:
Perimeter because you add up all the sides.
Area because you multiply length and width
Answer: 1, 3, and 4 can form triangles. The rest can not.
Step-by-step explanation:
on triangles 1, 3, and 4, the 2 smaller sides added together are greater than the longer side.
1.3 kg = 1,300 grams
1300 - 700 = 600 grams
So 1.3kg is 600 grams heavier than 700 grams.
Answer:
Step-by-step explanation:
F(x)=√(x-2)
F'(x)=1/(2√(x-2))
