arlik [135]

Answer:

  √7 ≈ 2.646

Step-by-step explanation:

The law of cosines is applicable. It tells you ...

  c² = a² + b² - 2ab·cos(C) . . . . . where a, b, c are triangle side lengths, and angle C is opposite side c.

Filling in the given information, you have ...

  c² = 2² + 3² - 2·2·3·cos(60°) = 4 + 9 - 12·(1/2) = 7

  c = √7 ≈ 2.646

The length of the third side is √7, about 2.646 units.

Jess shares £60 in the ratio 3:4
Nataliya [291]

Answer:

Amount of money share by Jess = £25.70

Another Amount of money share by Jess = £34.3

Step-by-step explanation:

Given:

Amount of money Jess have = £60

Sharing ratio = 3 : 4

Find:

Amount of money share by Jess

Computation:

Sharing amount = Shared ratio / Sum of ratio

Amount of money share by Jess = 60[3/(3+4)]

Amount of money share by Jess = 60[3/(7)]

Amount of money share by Jess = 180 / 7

Amount of money share by Jess = £25.70

Another Amount of money share by Jess = £60 - £25.70

Another Amount of money share by Jess = £34.3

What is the value of x
goblinko [34]

Answer:

52/3

Step-by-step explanation:

Use basic Thales therom,

\frac{3x}{4x}=\frac{3x+7}{5x-8}\\\\\frac{3}{4}=\frac{3x+7}{5x-8}\\

Cross multiply,

3*(5x-8)=4*(3x+7)

3*5x - 3*8 = 4*3x + 4*7

15x - 24 = 12x +28

Add 24 to both sides

15x = 12x + 28 + 24

15x = 12x + 52

Subtract 12x from both sides

15x-12x =52

3x = 52

Divide both sides by 3

x = 52/3
