2(x-5)+8=4<br><br>what does x equal?​
Ostrovityanka [42]

Answer:

x=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(x−5)+8=4

(2)(x)+(2)(−5)+8=4(Distribute)

2x+−10+8=4

(2x)+(−10+8)=4(Combine Like Terms)

2x+−2=4

2x−2=4

Step 2: Add 2 to both sides.

2x−2+2=4+2

2x=6

Step 3: Divide both sides by 2.

2x/2 = 6/2

x=3

Irina18 [472]

The measure of angle A in the isosceles triangle ABC is equal to 120 degrees.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

In the triangle ABC, AB = BC = 8. Triangle ABC is an isosceles triangle and ∠B = ∠C = 30° (base angles are equal).

∠A + ∠B + ∠C = 180° (sum of angles in a triangle)

∠A + 30 + 30 = 180

∠A = 120°

The measure of angle A in the isosceles triangle ABC is equal to 120 degrees.
