Answer:
Height of tree is 
<em>15 m.</em>
<em></em>
Step-by-step explanation:
Given that student is 20 m away from the foot of tree.
and table is 1.5 m above the ground.
The angle of elevation is: 34°28'
Please refer to the attached image. The given situation can be mapped to a right angled triangle as shown in the image.
AB = CP = 20 m
CA = PB = 1.5 m
= 34°28' = 34.46°
To find TB = ?
we can use trigonometric function tangent to find TP in right angled 
Now, adding PB to TP will give us the height of tree, TB
Now, height of tree TB = TP + PB
TB = 13.72 + 1.5 = 15.22 <em>15 m</em>
Answer:
32
Step-by-step explanation:
The problem above can be solved by using the <em>multiplication operation</em>.
Given: 400 people
8% of the people with green eyes
Let's solve:
Let x be<em><u> the number of people with green eyes.</u></em>
x = 400 x 8%
x = 400 x (0.08)
x = 32
So, the number of people surveyed with green eyes is 32. The rest of the surveyed people (368) have a different eye color.
Answer: the answer is 180 
Step-by-step explanation:
Area of a rectangle multiply length times base. 15 x 12 = 180. Hope this helps!
