Answer:

The measure of angle 2 is 45 degrees

Step-by-step explanation:

Mathematically, when two angles are supplementary, the sum of these angles will be equal to 180 degrees

Let the measure of angle 2 be x

The measure of angle 1 is 3 times this and that will be 3 * x = 3x

The sum of both will be 180

x + 3x = 180

4x = 180

x = 180/4

x = 45

The solution set, all real numbers greater than or equal to one, proves which of the following inequality statements to be true?
Juliette [100K]

Answer:

-5x ≤ 6x - 11

Step-by-step explanation:

Solving inequalities involves the same steps as equations with the exception that when multiplying or dividing by a negative coefficient of the variable, the inequality sign will flip.  The solution to one of the inequalities given must be x ≥ 1.  Given this answer, you can solve each to find the matching inequality:

-5x ≥ 6x - 11 or -11x ≥ -11 or x ≤ 1 (flip the sign due to negative coefficient)

-5x ≤ 6x - 11 or -11x ≤ -11 or x ≥ 1 (flip the sign)

5x ≤ 6x + 11 or -x ≤ 11 or x ≥ -1

-5x ≤ 6x + 11 or -11x ≤ 11 or x ≥ -1

Please help me do this maths calculation ​
WINSTONCH [101]

Answer:

x = y^{2} - 4y + 12

Step-by-step explanation:

y = 2 + \sqrt{x-8}

Put the 2 on the other side

y - 2 = \sqrt{x-8}

Square both sides

(y-2)^{2} = x - 8

Expand the brackets

y^{2} - 4y + 4 = x-8

Move 8 to the other side

x = y^{2} - 4y + 12
