Answer: 40/41
Step-by-step explanation:
The cosine can be represented as adjacent/hypotenuse. Thus, the cosine of C is 40/41
Substituting m for 9
h(9) = 9^2 - 3*9
h(9) = 81 -27
h(9) = 54
Third option!
Answer:
first construct the base of 5.3 cm(bc)
make an angle of 60° in B [ use protactor or compass]
then construct the AB of 8 cm
now measure AD 5.3 cm
join D and C
