Help me please, i can't solve it

The length of BC is 2.30

Explanation:

It is given that AB = 3 and ∠A = 50°

To find the length of BC, let us use the sine formula.

The formula is given by

where , opp = BC and hyp = AB

Thus, substituting these in the formula, we get,

From the diagram, the value of AB is 3.

Substituting the value and simplifying the expression, we have,

Multiplying both sides by 3, we get,

Rounding the answer to the nearest hundredth, we have,

Thus, the length of BC is 2.30

42

step-by-step explanation:

256/6=42

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
