Answer:
x = 50°
y = 50°
z = 80°
Step-by-step explanation:
working out x:
angles on a straight line add up to 180°
x + 130° = 180°
subtract 130 on both sides
x = 180° - 130°
x = 50°
working out y:
two vertical lines means that both sides are equal, so both angles are also equal (it's an isosceles triangle). This means that y is the same angle as x = 50°
y = 50°
working out z:
the sum of a triangle add up to 180°
add up the angles of x and y and equate to 180°
50 + 50 + z = 180
100 + z = 180
subtract 100 on both sides
z = 180 - 100
z = 80°

Answer:
314
Step-by-step explanation:
Hi there!
The slope of this line is 5*. Therefore, the slope of any line that is parallel to y = 5x + 3 is 5 as well (since parallel lines have the same slope).
* In a linear formula in standard form y = ax + b the a represents the slope of the line. In other words: in a linear formula in above form, the slope is the number in front of x.
Answer:
<h2>(-36 : 4) + 9 = -36 : 4 + 9 = 0</h2>
Step-by-step explanation:
9 more than the quotient of -36 and 4.
<em>the quotient of -36 and 4 → -36 : 4 = -9</em>
<em>9 more → + 9</em>
9 more than the quotient of -36 and 4 → -36 : 4 + 9 = -9 + 9 = 0
