Two solutions were found :
1. z = 2
2. z = -1
Step-by-step explanation:
Answer:
x= 113
y= 67
z= 49
Step-by-step explanation:
a triangle equals to 180° so lets start with the triangle that has two given degrees
28 + 39 + x = 180 solve
x = 113
no we can find y by using x + y = 180 since it's a straight line
we know the value of x so 113 + y = 180. solve.
y= 67
now do the same thing we did from the start since we have two given degrees on the other triangle.
67 + 64 + z = 180
z= 49
You subtract the x from both sides of the equation so it will then be -3y = -2x - 6. You then divide each number by -3, -3y divided by -3, -2x divided by -3, and the - 6 divided by negative 3. It would equal y = 2/3x + 2
Answer:
x^2 - 2x + 4
Step-by-step explanation:
Answer:
<h2>x = 14, z = 65</h2>
Step-by-step explanation:
The angles (5x - 5)° and (6x + 31)° are supplementary angles.
Supplementary Angles add up to 180°.
Therefore we have the equation:
5x - 5 + 6x + 31 = 180 <em>combine like terms</em>
(5x + 6x) + (-5 + 31) = 180
11x + 26 = 180 <em>subtract 26 from both sides</em>
11x = 154 <em>divide both sides by 11</em>
x = 14
The angles (5x - 5)° and z° are vertical angles.
Vertical angles are congruent.
Therefore we have the equation:
z = 5x - 5 <em>put x = 14 to the equation</em>
z = 5(14) - 5
z = 70 - 5
z = 65
