Answer:
I'm sorry, I can help only with this one x = 20°
Step-by-step explanation:
2x + 5° + 4x + 15° + 2x = 180°
8x = 180° - 5° - 15°
8x = 160°|÷8
x = 20°
I am pretty sure it is 39 but I am not exactly sure. You might want someone else to solve this too. I did 27*.45=12.15 then I did 12.15+27=39.15 then I rounded the answer to the nearest whole number.
I hope this helped you:)
The lesser number is 13.
Step-by-step explanation:
Step 1 :
Let x represent the first number and y represent the second number
Given, sum of 2 numbers = 30
So we have,y + x = 30
The difference of the 2 numbers = 4
so x - y = 4
Step 2 :
Adding the 2 equations obtained in step 2 we have,
2 x = 34 => x = 17
x + y = 30 => y = 30-x= 30 - 17 = 13
Step 3 :
Answer :
So 17 and 13 are the 2 numbers.
The lesser number is 13.
