Answer:
I. First number, a = 40.
II. Second number, b = 50.
III. Third number, c = 120.
Step-by-step explanation:
Let the three numbers be a, b and c respectively.
Given the following data;
Translating the word problem into an algebraic equation, we have;
a + b + c = 210
b = a + 10
c = 3a
Substituting the value of b and c into the equation, we have;
a + a + 10 + 3a = 210
5a + 10 = 210
5a = 210 - 10
5a = 200
a = 200/5
<em>a = 40</em>
To find the value of b;
b = a + 10
b = 40 + 10
<em>b = 50</em>
To find c
c = 3a
c = 3*40
<em>c = 120</em>
I THINK ITS B or A BUT I AM NOT SURE
<span>You multiply both the numerator and the
denominator by the same number (but not 1 or 0), but don't
simplify. 3/10 is your fraction, and you could multiply the top and
bottom numbers by 2 to get 6/20.
I hope I helped please leave thanks

The answer is 52. remember PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction) you can use "please excuse my dear aunt sally" to help you remember! :)
Never,because obtuse angle is an angle measuring between 90 and 180
and if an angle measures 180 then it is a straight angle
