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 :)
Answer:
Step-by-step explanation:
Considering the system of the equations
Divide both sides by 2
Answer:
hello :
the perimeter is : p = 2(w +l)
w :width.... l : the length
54 = 2(w + 23.5)
w+23.5 = 27
w =23.5 ft
Answer:
Sum = 15 8/15, Difference = 1 2/15
Step-by-step explanation:
8⅓, 71/5
A. Sum
8⅓ + 7 1/5
Convert to improper fraction
25/3 + 36/5
Find the LCM of 3 and 5. The result is 15. Divide 15 by the denominator of each fraction and multiply the result obtained with the numerator. The result is shown below:
[(25×5) + (36×3)] / 15
[125 + 108] / 15
233 / 15
Convert to mixed fraction
15 8/15
B. Difference
8⅓ – 7 1/5
Convert to improper fraction
25/3 – 36/5
Find the LCM of 3 and 5. The result is 15. Divide 15 by the denominator of each fraction and multiply the result obtained with the numerator. The result is shown below:
[(25×5) – (36×3)] / 15
[125 – 108] / 15
17 / 15
Convert to mixed fraction
1 2/15
SUMMARY:
Sum = 15 8/15, Difference = 1 2/15
