<u>Answer:</u>

4x + 3y = 12

<u>Step-by-step explanation:</u>

At x-intercept, y = 0.

∴ When we substitute y = 0 into the equation, x should equal 3.

• 1st equation:     3x + 4(0) = 12  ⇒  x = 4       ❌

• 2nd equation:  4x + 3(0) = 7    ⇒  x = 7/4    ❌

• 3rd equation:   3x + 4(0) = 7    ⇒  x = 7/3    ❌    

• 4th equation:   4x + 3(0) = 12   ⇒  x = 3       ✅

This means the 4th option is the correct one.

To check, we can replace x = 0 into the 4th equation to see if the y-intercept value comes out to be 4:

4(0) + 3y = 12    ⇒    y = 4     ✅

In a right triangle one leg measures a quarter of the other, how much do its acute angles measure? with procedure please​
KATRIN_1 [288]

Answer:

The answer to your question is 14° and 76°

Step-by-step explanation:

Data

leg 1 = x

leg 2 = x/4

angle 1 = ?

angle 2 = ?

Process

To solve problem use trigonometric functions. We must use the trigonometric function that relates both legs (tangent).

    tangent Ф = Opposite side / Adjacent side

-Substitution

    tan Ф = (x/4) / x

-Simplification

    tan Ф = x / 4x

    tan Ф = 1/4

-  Find Ф

     Ф = tan⁻¹(1/4) =  14°

- Find the other acute angle

  The sum of the internal angles in a triangles equals 180°

       Ф + Ф₁ + 90° = 180

-Solve for Ф₁

        Ф₁  = 180 - 90 - 14

-Result

        Ф₁ = 76°

You need to work out the area so

Area of a rectangle is l x b

So

A= l x b
A= 8 x 4
A= 32
