Answer: 15 feet
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Tan α = opposite side / adjacent side
Where α is the angle of elevation to the sun, , the opposite side (x) is the height of the tree, and the adjacent side is the length of the shadow.
Replacing with the values given:
Tan 31 = x /25
Tan 31 (25) =x
x = 15 feet
Feel free to ask for more if needed or if you did not understand something.
Answer:
2 kg
Step-by-step explanation:
15/100 x = 0.3
x = 0.3 * 100/15
x = 2
Answer:
1.y= -2x+3 slope -2
2. y= -4/5x-6 slope -4/5
3. y= 1/3x=4 slope 1/3
4. y= x+8 slope 1
5. y= 4x slope 4
6. y= 3/2x+7 slope 3/2
7. y= 3/2x+5 slope 3/2
8. y= -1/5x-3 slope -1/5
