Let the angles be x

  • ∠QRT = x
  • ∠TRS = x

We are taking both angles as x because they are equal!

\mathcal{∠QRT  + ∠TRS  = 180 \degree}

\tt \: x + x = 180 \degree

\tt \: 2x = 180 \degree

\tt \: x = 90 \degree

blsea [12.9K]
The answer is C. $5,355

In order to find this amount you need to find how much he makes in each month individually. We'll start with month one where he sold $13,500 worth of software. Since that number is under $20,000 we know that he makes 10%. So to find his earnings, we simply multiply the told sold by the percentage. 

$13,500 * 10% = $1,350

Now we need to find the amount for month two. Since he sold $26,700, which is more than $20,000 we know that he gets the 15% of the amount sold. Similarly to last time, we'll multiply the two together. 

$26,700 * 15% = $4,005

Now you can combine the two of them to find the overall amount. 

$1,350 + $4,005 = $5,355

Chloe works for an estate agent.
Lunna [17]

Answer:

£24,980

Step-by-step explanation:

total pay = monthly salary + percent of annual profit + £250 bonus

monthly salary = £1,850

annual salary = 12 × £1,850 = £22,200

agency income = £356,000

agency costs = £280,000

annual profit = income - costs = £356,000 - £280,000 = £76,000

percent of annual profit = 3% × £76,000 = 0.03 × £76,000 = £2,280

£250 bonus = 2 × £250 = £500

total pay = monthly salary + percent of annual profit + £250 bonus

total pay = £22,200 + £2,280 + £500

total pay = £24,980

x=280

We have, 15% × x = 42

or,

15

100

× x = 42

Multiplying both sides by 100 and dividing both sides by 15,

we have x = 42 ×

100

15

x = 280

If you are using a calculator, simply enter 42×100÷15, which will give you the answer.
