C = 53.4 ft
A = 227 ft2
Answer:
611 square miles
Step-by-step explanation:
Area of triangle = (1/2)*a*b*sinC (formula when u are not given the height of the triangle, but u are given with the angle.)
= (1/2)*30*47*sin(60°)
= 610.54 square miles (2 d.p)
≈611 square miles (rounded to nearest mile)
:)
2x-2+x+5=90
3x+3=90
-3 -3
3x/3 =87/3
x=29
(6•x) + 7 = 8
6x + 7 = 8
6x = 1
X = 1
