Using the Sine Rule:-
20 /sin 45 = BC / sin 30
BC = 20 sin 30 / sin45
= 20 * 1/2 / 1 / sqrt2
= 20 * 1/2 * sqrt2
= 10 sqrt2 answer
Answer:
=4.1d+5.4h−18
Let's simplify step-by-step.
8h−0.9d−18+5d−2.6h
=8h+−0.9d+−18+5d+−2.6h
Combine Like Terms:
=8h+−0.9d+−18+5d+−2.6h
=(−0.9d+5d)+(8h+−2.6h)+(−18)
=4.1d+5.4h+−18
Answer:
22.9
Step-by-step explanation:
I believe the answer is 116.
23-8=15
8*15=120
sqrt2=4
the number 120-4=116
that’s what i got not sure if that is correct
