Answer:
(24x + 24) units
Step-by-step explanation:
A rectangle is a shape that has four sides in which all angles are equal and opposite sides are equal and parallel to each other. The perimeter of a rectangle is the sum of all its sides. Since opposite sides are equal, the perimeter is given as:
Perimeter = 2(length + width)
Since the sides of the rectangle are 2 x + 11 units long and 10 x + 1 units long. Hence:
Perimeter = 2(2x + 11 + 10x + 1)
Perimeter = 2(2x + 10x + 11 + 1) = 2(12x + 12)
Perimeter = (24x + 24) units
P=44.6
P=a+b+√a^2+b^2=11+15+√11^2+15^2≈44.6
Answer:
The total height of coconut Tree = H + 10ft = 11.77 ft
Step-by-step explanation:
Given as,
The height of Kalei = 6ft
The distance of Kalei from the coconut Tree = 10 feet
Angle of elevation of kalei up to the coconut on tree = 30°
<u>Note : look at the pic attache </u>
From figure it is mention that
Total height of Tree = 6 ft + H
So, Tan 30° = 
Tan 30° = 
∴ H = 10 Tan 30° = 10 × 0.577 Note : tan 30° = 0.577
i.e H = 5.77 ft
Hence the total height of coconut tree = 6 + 5.77 = 11.77 ft Answer
-1(x) or -x. In your case, -1(-7).
