Well assuming that this would be a typical triangle, and not a right angle one, knowing that the sum of all sides adds up to 180 degrees, simply add all of the expressions and one value and make it equal to 180, and then solve for x.

(6x-1) + (X+14) + 20 = 180
6x - 1 + X + 14 = 160
7x - 1 + 14 = 160
7x + 13 = 160
7x = 147
X = 21.

Now solve for the angles by plugging in X.

A = 6x - 1 = 6(21) - 1 = 125 degrees
C = X + 14 = (21) + 14 = 35 degrees.

I believe these are the solutions.

Answer:

t $\leq$ 24

Step-by-step explanation:

we can add 5 to both sides

-t/6 $\geq$ -4

multiply both sides by 6

-t $\geq$ -24

divide by -1, when dividing by a negative, the inequality flips

t $\leq$ 24

– 72 = 3(- 4x – 8) Need help

Finger [1]

Answer:

x = 4

Step-by-step explanation:

Step 1: Write equation

-72 = 3(-4x - 8)

Step 2: Solve for x

Distribute 3: -72 = -12x - 24

Add 24 to both sides: -48 = -12x

Divide both sides by -12: x = 4

Step 3: Check

Plug in x to verify if it's a solution.

-72 = 3(-4(4) - 8)

-72 = 3(-16 - 8)

-72 = 3(-24)

-72 = -72
