Answer:

x² = 17² - 8²

Step-by-step explanation:

Pythagoras theorem

Diagonal ² = length² + width²

Rearrange to get length in its own

Length ² = diagonal ² - width²

Replace length with x, diagonal with 17 and width with 8

x² = 17² - 8²

Answer:

Step-by-step explanation:

Join OB.

∠A=∠A  (common)

\frac{AP}{AO} =\frac{\frac{1}{2} AO}{AO} =\frac{1}{2} \\\frac{AQ}{AB} =\frac{\frac{1}{2} AB}{AB} =\frac{1}{2} \\\frac{AP}{AO} =\frac{AQ}{AB}

∴ ΔAPO and ΔAOB are similar.

\frac{PQ}{OB} =\frac{1}{2} \\

∠P=∠O

∠Q=∠B

So PQ║OB

Similarly RS║OB

∴PQ║RS

Hi!

We can see the river is a straight line.

This means that the angles that fall upon it are supplementary angles, and will add up to 180 degrees.

Therefore:

x+2x+21=180

Combine like terms:

3x+21=180

Subtract 21 from both sides:

3x=159

Divide both sides by 3:

x=53

Therefore, the value of x is 53 degrees.
