A , B and C form a triangle where ∠ B A C = 90 ∘ . A B = 0.5 mm and B C = 15.4 mm. Find the length of A C , giving your answer r

denpristay [2]

Answer:

15•4 mm

Step-by-step explanation:

using sine rule

a÷ sinA=c ÷sinC

15•4÷sin90=0•5÷sinC

sinC =0•5 × sin90 ÷ 15•4

C =1•9°

A+B+C= 180

90+B+1•9=180

B= 88•2°

b÷sinB = a÷sinA

b÷sin88•2= 15•4÷sin90

b=sin88•2 ×15•4 ÷sin90

b =15•39

to 1 dp

b =15•4 mm

a pair of jeans originally cost $140 and are now on sale for 65% off. what is the sale price of the jeans

Andrei [34K]

Answer:

$49

Step-by-step explanation:

<u><em>Method 1</em></u><u><em>:</em></u>

100% - 65% = 35%

$\frac{y}{140}: \frac{35}{100}$

y · 100 = 35 · 140

100y = 4900

100y ÷ 100 = 4900 ÷ 100

y = 49

<u><em>Method 2</em></u><u><em>:</em></u>

$\frac{y}{140}: \frac{65}{100}$

y · 100 = 65 · 140

100y = 9100

100y ÷ 100 = 9100 ÷ 100

y = 91

$140 - $91 = $49
