Sum of interior angles of any triangle is 180
so:
x + (3x+25) + (x -5) = 180
5x + 20 =180 5x =160
x = 32
∠G = 3x + 25 = 121
The equation
(y + 5) + y = 6
shows the substitution method being used to solve the system of linear equations. So the correct option among all the options given in the question is option "D".
For a better explanation, let us first write down the two equations given in the question.
x + 5 = 6
and
x = y + 5
Now the thing that has been done is that the value of x in the first equation has been replaced by the value of x that is given in the second equation. this is actually the substitution method of solving equations.
N/-2=-16
Aka
Negative number(n) is divided by negative two equals negative sixteen
It gets you closer to your answer.
Ex: 11×2-- Round 11 to 10 and then multiply and get 20. But if you get some answer like 50, you know it is wrong. But the answer is 23
Answer: 50.24 mm
Step-by-step explanation:
Circumference= 2πr
C = 2 x 3.14 x 8mm
C = 50.24 mm
