Answer:

GH = 7 $\sqrt{2}$

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = $\frac{1}{\sqrt{2} }$

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{HI}{GH}$ = $\frac{7}{GH}$ = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

GH = 7 $\sqrt{2}$

Answer:

The total earning of commission on sales of 85, 000 will be:

$3500+1050=4550$

Step-by-step explanation:

Total sales earning = 85,000

As salesperson earns 5% commission the first 70,000.

$\frac{5}{100}\:\times \:70\:000=3500$

As the salesperson earns 7% commission on the sales over 70,000.

As 15000 is the sales earning on which he will get commission 7%.

Because

85,000 - 70,000 = 15000

So the 7% earning of salesperson will on 15000 will be:

$\:\frac{7}{100}\:\times \:15\:000=1050$

Therefore, the total earning of commission on sales of 85, 000 will be:

$3500+1050=4550$
