Identify at least one pair of the following angles

Dahasolnce [82]

Answer:

Alternate exterior angles : ∠g = ∠b , ∠h = ∠a (opposite sides and on outer side)

Alternate interior angles : ∠c = ∠f , ∠e = ∠d (opposite sides and on inner side)

Consecutive interior angles : ∠c = ∠e , ∠d = ∠f (same sides and on same line)

Corresponding angles : ∠e = ∠a, ∠f = ∠b, ∠g = ∠c, ∠h = ∠d (same sides on the line)

Linear pairs : ∠c and ∠e, ∠d = ∠f, (they add to 180)

Vertical angles : ∠c =∠b, ∠d = ∠a, ∠g=∠f, ∠e = ∠h (vertical angles)

Z + 6 over 3 = 2z over 4

Black_prince [1.1K]

$\frac{z + 6}{3}$ = $\frac{2z}{4}$ Multiply both sides by 3
z + 6 = $\frac{(3)2z}{4}$ Multiply both sides by 4
(4)z + 6 = (3)2z Simplify
4z + 24 = 6z Subtract 4z from both sides
24 = 2z Divide both sides by 2
12 = z Flip the sides to make it easier to read
z = 12

ASHA 777 [7]

Answer:

$x=10$

Step-by-step explanation:

Notice that all three sides of the given triangle has one tick mark.

This means that all three sides are congruent, meaning that we have an equilateral triangle.

And for equilateral triangles, all three angles are also congruent.

So:

$\angle CBA=\angle BAC=\angle ACB$

Also, recall that the interior angles of a triangle is always 180. Thus:

$\angle CBA+\angle BAC+\angle ACB=180$

Substitute:

$\angle CBA+\angle CBA+\angle CBA=180$

Combine like terms:

$3\angle CBA=180$

Substitute:

$3(6x)=180$

Multiply:

$18x=180$

Thus:

$x=10$

And we are done!

(Will l give 25 points!) Solve the system of linear equations by substitution. -8x + y = 5 and 5x - y = 3

Serggg [28]

Answer:

x = -8/3 and y = -49/3

Step-by-step explanation:

(Step 1) To solve using substitution, you first need to isolate a variable in one of these equations. I chose to isolate "y" in the following equation.

-8x + y = 5 <--- Original equation

y = 5 + 8x <--- Add 8x to both sides

(Step 2) Now, substitute (5 + 8x) for "y" in the second equation.

5x - y = 3 <--- Original equation

5x - (5 + 8x) = 3 <--- Substitute 5 + 8x for "y"

5x - 5 - 8x = 3 <--- Distribute (-) in the parentheses

-3x - 5 = 3 <--- Combine terms with "x"

-3x = 8 <--- Add 5 to both sides

x = -8/3 <--- Divide both sides by -3

(Step 3) Since you know the value of "x", plug it into one of the equations to solve for "y".

y = 5 + 8x <--- Original (rearranged) equation

y = 5 + 8(-8/3) <--- Plug (-8/3) for "x"

y = 5 - 64/3 <--- Multiply

y = 15/3 - 64/3 <--- Convert 5 into a fraction

y = -49/3 <--- Subtract

(Step 3.5) You can check your work by plugging "y" into the other equation to see if the answer for "x" is the same.

5x - y = 3 <--- Original equation

5(-8/3) - y = 3 <--- Plug (-8/3) for "x"

-40/3 - y = 3 <--- Multiply

-40/3 - y = 9/3 <--- Convert 3 into a fraction

-49/3 - y = 0 <--- Subtract both sides by 9/3

-49/3 = y <--- Add both sides by "y"

The value of the system of equations is x = -8/3 and y = -49/3.
