Round your answer to the nearest hundredth.

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

=

10.989909677818 × 4

=21.97982

perimeter =a + b + c

=10.989909677818 + 4 + 11.695217600652

=26.68513

inradius =

a × b

a + b + c

=

43.959638711274

26.685127278471

=1.64735

circumradius =

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
