Use cosine rule:

c²=b²+a²-2ba cosC

Right triangle = 90 degrees
cosine 90 degrees = 0

c²=28²+15²-2×28×15×0
c²=28²+15²
c=√1009
c=31.8 in

What is the answer if <br> Increase 12% by 30%
mrs_skeptik [129]

Answer:

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

30% = 30/100 = 30 ÷ 100 = 0.3.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 30% of its value.

Calculate the New Value

New value =

12 + Percentage increase =

12 + (30% × 12) =

12 + 30% × 12 =

(1 + 30%) × 12 =

(100% + 30%) × 12 =

130% × 12 =

130 ÷ 100 × 12 =

130 × 12 ÷ 100 =

1,560 ÷ 100 =

15.6

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 12 =

15.6 - 12 =

3.6
