Answer:
31.7 cm²
Step-by-step explanation:
The area (A) of the triangle is calculated as
A =
absinC
where a, b are the 2 sides given and C the angle between them
∠ C = 180° - (72 + 59)° = 180° - 131° = 49° , thus
A = 0.5 × 12 × 7 × sin49° ≈ 31.7 cm² ( to 1 dec. place )
Answer:
hello :
If f(x)=x-2 and g(x)=1/2x,
g(f(x)) = g ( x - 2 )
= 1/2(x-2)
g(f(x)) = (1/2)x - 1
The answer is D. It is rarely stated explicitly
Answer:
250 ft
Step-by-step explanation:
circumference of circle 'C' is defined as
C = 2πr
250π = 2πr
r = 250π/2π
r= 125
d = 2r = 2×125 = 250
.
diameter of the given circle is 250 ft
