Answer 1

1)

NP² = MN² + MP²

NP² = 12 + 36

NP² = 48

NP = 4√3 cm

2)

QR² = QP² - PR²

QR² = 576 - 144

QR² = 432

QR = 12√3 cm

3)

∡B = 30° => T30° => BC = 2AC = 2·8 = 16 cm

AB² = BC² - AC²

AB² = 256 - 64

AB² = 192

AB = 8√3 cm

4)

∡E = > ∡F = 30°

T30° => DE = FE/2 = 12/2 = 6 cm

DF² = FE² - DE²

DF² = 144 - 36

DF²² = 108

DF = 6√3 cm
