To solve all of these, you put the expressions you've been given into an equation that equals whatever number the sheet tells you is the sum of the angle measures. Then you just substitute it in to find the angle measures. I'll do the first one for you but tell me if you want me to do the rest:
2k + k + 45 = 180
3k + 45 = 180
- 45
3k = 135
÷ 3
k = 45°
45 × 2 (2k) = 90
Again let me know if you want the answers and working to the other two :)
$8,400
Explanation:
Amount repaid each month = $150
Number of Periods for which amount was paid = 10 months
Amount left after 10 months payment = $6900
The total amount paid = $150 × 10 = $1500
Amount left = $6900
Total debt amount:
(Total Amount left + total amount paid )
$(6900 + 1500)
Answer:
0.1
Step-by-step explanation:
100% - 20% = 0
77% - 20% = 0
100% - 77% = 0.1
Answer:
Rational
Step-by-step explanation:
The definition of rational is that it can be written as a fraction where the top and bottom are integers (the bottom integer not 0).

43/10 is written in that form since 43 and 10 are both integers.
2/3 + 1/2 is 7/6
Hope this helps!
