Answer:
The angle of elevation is 36.87 degrees
Step-by-step explanation:
see the attached figure to better understand the problem
In the right triangle ABC of the figure
----> by CAH (adjacent side divided by the hypotenuse)
substitute the given values
Answer:
A
Step-by-step explanation:
Let's assume the first pool to have dimensions 3.0 by 2.0
The second pool being 2.1 times the first will have dimensions 6.3 * 4.2
The area of the first pool is 6.0 and that of the second is 26.46
making the area of the second pool 4.41 times that of the first.
Answer:
24 sq cm
Step-by-step explanation:
According to theorem of area if parallelogram and triangle, if the triangle and a parallelogram lie between two parallel line and their base is same then, the area of triangle is half of the area of the parallelogram. so here the parallelogram PTRS and the triangle PTR lie between same parallel lines PT and RS and base is also same PT. so area of PTR is 12sq cm. Again, triangles PTR and TRQ lie between same parallel lines PQ and SR and same base PQ. so their area also same that is 12 sq cm. Now, area of PQR = area of PTR + area of TRQ = 12 + 12 sq cm = 24 sq cm.
4 - 5x = 59
Subtract 4 from both sides:
-5x = 55
Since x is being multiplied by -5, the next step is to divide both sides by -5.
Answer:
Step-by-step explanation:
an equation is : y = 10x+b
calculate b : this line passes by : (7;1) when x =7 y = 1
so : 10(7)+ b=1
b= -69
so : y = 10x-69
