Step-by-step explanation:
This is a parallelogram. What we know about the diagonals is that they intersect each other at their midpoints. In other words, QT = ST, and PT = RT. So that gives us 2 equations:
If QT = ST, then
2x = y + 3
If PT = RT, then
x + 5 = y Solving by substitution, plug x + 5 in for y in the first equation.
2x = x + 5 + 3 and
2x = x + 8 and
x = 7 Now plug in 7 for x to solve for y:
If x + 5 = y, then
7 + 5 = y and
y = 12

Answer:
comparing fossils with other engerys:
Most alternatives energy sources doesn't have as much pollution produce like fossil fuel does,
Fossil comes from underground or persevered by nature, when others can be made by renewable resources, such as Wind(windmills) , sun (solar), and water (those rolly things)
Answer:
<1 = 107°
<7= 92°

<h2>
What is a hexagon?</h2>
A hexagon is a type of polygon with six sides, six vertices and six angles. It's two dimensional and closed as well.
<h3>Finding the missing angles:</h3>
Note:
<h3>Angles on a straight line equal 180°</h3>
Therefore,
88° + <7 = 180°
Subtract 88° from bothsides
88° - 88° + <7 = 180°- 88°
<7 = 92°
164° + < 6 = 180°
subtract 164° from bothsides
164° + < 6 = 180°
164° - 164° + < 6 = 180°- 164°
< 6 = 16°
118° + < 4 = 180°
subtract 118° from bothsides
118° - 118° + < 4 = 180 - 118°
< 4 = 62°
To find angle2
Note:
<h3>Sum of exterior angles of a polygon is equal 360°</h3>
64° + 62° + 57° + <2 + 88° + 16° = 360
combining like terms
64° + 62° + 57° + 88° + 16° + <2 = 360°
287° + <2 = 360°
subtract 287° from bothsides
287°- 287° + <2 = 360° - 287°
<2 = 73°
Calculating for angle 1
< 1 + 73° = 180°
Subtract 73° from bothsides
<1 + 73° - 73° = 180 - 73°
<1 = 107°
Therefore,
< 1 = 107°
< 7 = 92°
