Answer:
x = -3
Step-by-step explanation:
2(x + 7) - 3 = 5 (given)
2x + 14 - 3 = 5 (Distributive Property)
2x + 14 = 8 (Addition Property of Equality)
2x = -6 (Subtraction Property of Equality)
x = -3 (Division Property of Equality)
Answer:
Tan(O) = 4/3
Step-by-step explanation:
According to SOH CAH TOA
cos theta = adj/hyp
cosO = 3/4
adj = 3
hyp = 5
Get the opposite
Using pythagoras theorem
opp^2 = hyp^2-adj^2
opp^2 = 5^2 - 3^2
opp^2 = 25-9
opp^2 = 16
opp = 4
Tan (O) = opp/adj
Tan(O) = 4/3
Hence Tan(O) = 4/3
