The interior angles of a triangle are

(x + 10) °

(3 x) °

(2 x + 30) °

. What is the value of

x

Özgür Özer Dec 17, 2015 Euclid's postulate: The sum of the measures of the interior angles of a triangle is 180 degrees.

(\times) x + 10 + 3 x + 2 x + 30 = 180

0 = 2 x + 3

x

if the sequence

1, 5, 2 x + 3

....is an arithmetic sequence?

https://socratic.org/questions/what-is-x-if-the-sequence-1-5-2x-3-is-an-arithmetic-sequence

x = 3

Explanation: If the sequence is arithmeic, then there is common difference between the consecutive terms.

d = T_{3} - T_{2} = T_{2} - T_{1}

(2 x + 3) - 5 = 5 - 1 we have an equation - solve it

Multiplicative inverse of

2 x + 3 + I

Z_{5} [x] / I

https://math.stackexchange.com/q/2068641

You need to use that

x^{2} + I = (- x - 2) + I

(2 a x^{2} + (3 a + 2 b) x + 3 b) + I = (a + 2 b) x + (3 b - 4 a) + I

a + 2 b \equiv 0 m o d 5

3 b - 4 a \equiv 1 m o d 5

. The solution is

a = 3

b = 1

How do you simplify

2 x + 3 + x

https://socratic.org/questions/how-do-you-simplify-2x-3-x

See a solution process below: Explanation: First, group like terms:

2 x + x + 3

Now, combine like terms:

2 x + x + 3 \Rightarrow

2 x + 1 x + 3 \Rightarrow
