Answer: 23
step by step:
The angle is 90 degrees
(2x+14) + (x+7) = 90
(2x+ x) + (14+7) = 90
3x+21 = 90 (subtract 21 from both sides)
3x+ 21 - 21 = 90 - 21
3x = 69 ( divide each side by 3)
x = 23
Step1. find the how much he buy he buy 45
step2. find the % the % is 4 move to decimal left 4% which is .04
step3. multilply the how much he buy or the % so this is that 45*.04=1.8
step4. what are they said they said tax is like add so we got 1.8+$45=46.8
so the answer is 46.8
look at what is the step and you understand the problem more easy way.
The answer for this problem is t=-6.957
