Consider the triangle. What shows the order of the angles from smallest to largest?

1 answer:

7 0

The order of the smallest to largest angle is angle B, then angle A and the largest is angle C. In a theorem of the Triangle Inequalities, the larger value of the distance, the larger the opposing angle is. To get the exact value of each angle, law of cosines can be used.

What ordered pair is a solution to y = x + 5 and x - 5y = -9? I also need to show the work.

Margarita [4]

Answer:

(- 4, 1 )

Step-by-step explanation:

Given the 2 equations

y = x + 5 → (1)

x - 5y = - 9 → (2)

Substitute y = x + 5 into (2)

x - 5(x + 5) = - 9 ← distribute and simplify left side

x - 5x - 25 = - 9

- 4x - 25 = - 9 ( add 25 to both sides )

- 4x = 16 ( divide both sides by - 4 )

x = - 4

Substitute x = - 4 into either of the 2 equations and evaluate for y

Substituting into (1)

y = - 4 + 5 = 1

Solution is (- 4, 1 )
