Given b=4 and ∠β=20°,
a = 10.98991
c = 11.69522
∠α = 70° = 1.22173 rad = 7/18π
h = 3.75877
area = 21.97982
perimeter = 26.68513
inradius = 1.64735
circumradius = 5.84761

Calculation Steps
The following is one way to perform the calculation. It may not be the best way.
c =
b
sin(β)
= 11.69522
a = √c2 - b2
= √11.6952176006522 - 42
= √120.77811472661
= 10.98991
∠α = 90° - ∠β
= 70° = 1.22173 rad = 7/18π
area =
a × b

= 21.97982
perimeter = a + b + c
= 10.989909677818 + 4 + 11.695217600652
= 26.68513
inradius =
a × b
a + b + c
=

Answer:
1.68m2
Step-by-step explanation:
The area of a rectangle is given by (l = length, w = width):
A=l* w
So, in this case, we just have to plug in the numbers.
A=2.1m*0.8m=1.68m2
So, the area of the rectangle is 1.68 m².

We have that
(x + 3)² + (y - 2)² = 36----------> (x + 3)² + (y - 2)² = 6²
we know that
the equation of a circle is of the form
(x-h)²+(y-k)²=r²
where (h,k) is the center and r is the radius
in this problem
the center of the circle is the point (-3.2) and the radius is r=6 units
so
if <span>shifting a circle right 3 units
then
the center will be-----> (-3+3,2)-------> (0,2)
therefore
the answer is the option
</span><span>B.The x-coordinate of the center of the circle increases by 3.</span>
Answer:
x = 36.87
Step-by-step explanation:
Find the length of the missing side.
x^2 + 12^2 = 15^2
x^2 + 144 = 225
x^2 = 81
x = 9
Now use the law of sines:
sin(90)/15 = sin(x)/9
Multiply each side by 9
9 * sin(90)/15 = sin(x)
0.6 = sinx
sin^-1 = 36.86989 rounded to 36.87
