If the area of one is 20, that the area of 30 is 20*30=600 square inches.
Answer:
93° (to the nearest degree)
Step-by-step explanation:
sum of the interior angles of a triangle = 180°
Find angle C first, then subtract angle C and angle B from 180° to find angle A.
Use the sine rule 
to find angle C:
Therefore,
angle C = 48.80523914...°
Angle A = 180 - 38 - 48.80523914...°
= 93.19476086..°
= 93° (to the nearest degree)
Answer:
Step-by-step explanation:
u got the first 2 correct
percentage of votes Adams claims :
so he claims 2681 out of 5281..
2681 / 5281 = (jeez...u dont want it rounded)...ok....its :
0.50766900208 which equals 50.766900208 % <==
the total of the percentages :
52% + 50.766900208% = 102.766900208 % <==
By definition, we have to:
In plane geometry, a rectangle is a parallelogram whose four sides are at right angles to each other. Opposite sides have the same length.
There is a proof that a quadrilateral is a rectangle:
1) Its parallel sides are the same.
2) Its two diagonals are the same, and they bisect each other at the common midpoint
3) Any rectangle can be inscribed in a circle, two of whose diameters coincide with the diagonals of the rectangle.
4) If all the angles of a quadrilateral are right angles, then it is a rectangle
Answer: 63.59cm²
Step-by-step explanation:
The area covered by the pitch will be gotten by finding the value of the area of the circle and this will be:
Area of q circle = πr²
where,
π = 3.14
r = radius = diameter/2 = 9cm/2 = 4.5cm
Area = πr² = 3.14 × 4.5²
= 3.14 × 20.25
= 63.59cm²
Therefore, the area covered by the pitch is 63.59cm²
