Answer:
PQ = 16.04cm
Step-by-step explanation:
θ = 76°
QR = 4cm
PQ = ?
Since it's a right angle triangle,
QR = adjacent
PQ = opposite
Tanθ = opposite/adjacent
Tan76 = pq / 4
PQ = 4tan76
PQ = 4 * 4.010
PQ = 16.04cm
4(4/5) + √(4/5) + 0.2 - 5(4/5)
= 16/5 + (2√5/5) + (1/5) - 4
= (16 + 2√5 + 1 - 20)/5
= (2√5 - 3)/5 or 0.29442719
