Answer:
52.5
Step-by-step explanation:
Since this is an isosceles triangle, the base angles are the same
The three angles add to 180
R+ T + S = 180
3x+30 + 3x+30 + 12x-15 = 180
Combine like terms
18x +45 = 180
Subtract 45 from each side
18x+45 - 45 = 180-45
18x =135
Divide each side by 18
18x/18 = 135/18
x = 7.5
We want angle R
R = 3x+30
= 3( 7.5) +30
22.5 +30

Answer:
I'm guessing it is 3x(9x20)=3x180=540
Step-by-step explanation:
The answer to a "sum and difference" problem is that the larger number is the average of those given: (43 +15)/2 = 29.
The smaller number can be computed any of several ways, but subtracting the difference works: 29 -15 = 14
The larger number is 29.
The smaller number is 14.
_____
You can let the numbers be a and b, and let the sum and difference be s and d. Then you have
.. a + b = s
.. a - b = d
Add these two equations, and you find "b" is eliminated:
.. 2a = s + d
.. a = (s + d)/2 . . . . . . the average of the sum and difference
.. b = a - d . . . . . . . . . from the second equation
This solution is generic. Even if you have to "show work" on such a problem, you can use this known result to check your work.
