Thanks this came in handy bc I'm a beginner
Step-by-step explanation:
here,,
a=3,b=10,C=120°
c^2=a^2+b^2-2ab cos120°
=(3)^2 +(10)^2 _2 (3)(10)(-1/2) [cos120°=-1/2]
=9+100-(-30)
=109+30
=139
c=(139 )1/2=11.79
c=12
Answer:
N: n = 5 sides
side length: a = 23.2 m
inradius: r = 15.966 m
circumradius: R = 19.7351 m
Area: A = 926.03 m2
perimeter: P = 116 m
interior angle: x = 108 °
exterior angle: y = 72 °
Description:
We use the calculations on the shape 16 and 23.2. Side length is 23.2. Pi is 16. calculate the numbers and all the answers are added above.

Answer:
1.5×2.5/2=1.875.
Step-by-step explanation:
We all know that area of triangle is base into hight upon 2.
-2y>12x-42
y<21-6x
so a is true
