Answer:
First, let one angle be a variable (eg: x) so that you can form expressions and solve.
Let the first angle be x°.
Then we can form expressions for the second and third angles using the information given.
First angle = x°
Second angle = (x + 10)°
Third angle = (3x)°
Since sum of angles in a triangle is 180°, we can form an equation.
x + (x + 10) + 3x = 180
Simplify and solve for x.
5x + 10 = 180
5x = 170
x = 34
Substitute x into the expressions to find the angles.
First angle = 34°
Second angle = 34 + 10
= 44°
Third angle = 3(34)
= 102°
Yes it is. If you put 2/5 in the calculator it will come up as 0.4
Answer:
7
Step-by-step explanation:
x/ 8 = 3
x = 3 x 8 = 21
~~~~~~~~~
3x / 8 =
3(21) / 8 = 7
remainder = "7"
I dont know if this is wht u want .... but i hope its right !
