<u>Let's take this problem step-by-step</u>:

<u>Both problems involve triangles</u>:

 ⇒ let's find out the sum of the interior angle w/ formula 180(n-2)

       <em> Total Interior Angle Sum of Triangle = 180(3-2) = 180</em>

<u>Let's solve the first problem (A)</u>

   ⇒ we know the total interior angle sum is 180 degrees

   ⇒ we know that two of the angles are 30 degrees and 90 degrees

        * <em>any angle with a square on them is 90 degrees</em>

   ⇒ therefore:

           30 + 90 + y = 180

              120 + y= 180

                    y = 60

<u>Let's solve the second problem</u>:

  ⇒ the angle opposite the exterior angle, 120 degrees, is on a flat line

        with it

        ⇒ therefore it is 60 degrees

            ⇒ two angles on a flat line equal 180 degrees

   ⇒ two angles are therefore 60 degrees

    ⇒ therefore:

                     60 + 60 + y = 180

                          120 + y = 180

                                  y = 60

<u>Answer:</u>

  • <u>(A) y= 60</u>
  • <u>(B) y =60</u>

Answer:

y=60° b=60°

Step-by-step explanation:

the sum of all degrees of interior triangle is 180

in the first one, 30° and 90° have been given.(that small square represent 90°)

so 180°-90°-30°=60°

in the second one, the 120° is on the other side of a line, a line has a degree of 180, therefore the interior angle is 60°, the same rule 180°-2*60°=60°

What is the equation of a horizontal line passing through the point (1, 14)?
Klio2033 [76]
The equation line passing through a point is understood to be parallel to the x-axis. In this case, the equation should be expressed as y = b where b is any number. Since y = 14 in the point (1,14), the equation of horizontal line passing through this point is y = 14.
