WILL MARK BRAINLIEST PLZ HELP Find the area of the triangle to the nearest tenth.
Question 12 options:

A)

457.9 square units

B)

40.7 square units

C)

229.0 square units

D)

143.1 square units

C

Step-by-step explanation:

Given a triangle with 2 known sides and the included angle , then

A = × 30 × 18 × sin122°

   = 15 × 18 × sin122°

   ≈ 229.0 units² ( to the nearest tenth )

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
