Answer:
The angle of elevation of the sun from the ground to the top of a tree is 
.
Step-by-step explanation:
As given
The sun from the ground to the top of a tree when a tree that is 10 yards tall casts a shadow 14 yards long.
Now by using the trignometric identity .
As figure is given below .
AB = Perpendicular = 10 yards
BC = Base = 14 yards
Putting all the values in the trignometric identity .
Therefore the angle of elevation of the sun from the ground to the top of a tree is .
Answer:
25/12
Step-by-step explanation:
So first change the mixed numbers into improper fractions. 5/4 ad 5/3. Then just multiply them. 25/12.
Answer:
11
Step-by-step explanation:
LN = LM + MN
=> 22 = 3z + 1 + 3z + 1
20 = 6z
z = 10/3
LM = (10/3)*3+1 = 11

<u>Answer:</u>
○ 
<u>Step-by-step explanation:</u>
Given the equation:
,
to solve for 
, we have to rearrange the equation to make its subject.
⇒ 
[expand brackets]
⇒ 
⇒ 
[add 
to both sides]
⇒ 
⇒ 
[subtract 96 from both sides]
⇒ 
⇒ 
[divide both sides by 20]
⇒ 
Answer:
the rate of change is -5.
Step-by-step explanation:
y = -5x - 3
-5 = rate of change
-3 = x intercept
