BC = 13.4

Step-by-step explanation:

its a law of cosines S-A-S

a² = b² + c² - 2bc cosA

a² = 12.6² + 4.6² - ( 2 * 12.6 * 4.6 * cos 90 )

a² = 179.92

a = sqrt (179.92)

a = 13.4

[tex]Area = 240 m^2[/tex]

Step-by-step explanation:

The area of the right triangle above = [tex]\frac{1}{2}*base*height[/tex].

Where,

base = 16 m

height = 30 m

Plug in the above values into the area formula:

[tex]Area = \frac{1}{2}*16*30[/tex]

[tex]Area = 8*30[/tex]

[tex]Area = 240 m^2[/tex]

XZY = 32 and XYZ = 116

Explanation:

Triangle XYZ is an isosceles triangle with XY = ZY and Angle YXZ = XZY

And YXZ = a = 32 degree

Which mean XZY also = 32 degrees

Find XYZ:

XYZ + YXZ + YZX = 180

XYZ + 32 + 32 = 180

XYZ + 64 = 180

XYZ = 180 - 64

XYZ = 116

£39.20

Step-by-step explanation:

→ Identify which ratio goes to each person

2 : 1 : 5

2 = Paul

1 = Colin

5 = Brian

→ Divide the total tip by the total sum of the ratio's

£78.40 ÷ ( 2 + 1 + 5 ) ⇔ £78.40 ÷ 8 = £9.80

→ Now we know one part is equal to £9.80 we multiply this number by each of the associated ratio's

Paul = £9.80 × 2 ⇔ £19.60

Colin = £9.80 × 1 ⇔ £9.80

Brian = £9.80 × 5 ⇔ £49

→ Minus Brian's tip against Colin's tip

£49 - £9.80 = £39.20
