<h3><u>Answer</u> :</h3>
It is clear from the diagram that,
⇒ (2x - 5) + (x + 5) = 180
⇒ (2x + x) + (5 - 5) = 180
⇒ 3x + 0 = 180
⇒ x = 180/3
⇒ x = 60°
◈ From the geometry of figure,
⇒ ㄥ6 = (2x - 5)
⇒ ㄥ6 = (2×60 - 5)
⇒ ㄥ6 = 120 - 5
⇒ <u>ㄥ6 = 115°</u>

Answer:
Distributive
Step-by-step explanation:
when you distribute 3 to x, 3y, and 5, you get 3x+9y+15, which is equivalent to the other expression when you simplify it
Answer:
D or answer 4 y=-5/2x+7
Step-by-step explanation:
Well we can first start of by finding the y-intercept.
Note that when x=0, you can find your y-intercept.
Knowing this, and looking at the table, 7 is the y-intercept because when y=7, x=0.
So we can eliminate choices 'a' and 'c,' or answers 1 and 3, because they have the y-intercept as -7, when it's just 7.
Please know that in the equation:
y = mx + b
y = y-coordinate or any given point
mx = slope
b = y-intercept
Now we must find slope
To find the slope we need to do:
(y2 - y1) / (x2 - x1) or rise/run
The two coordinates I choose to use is (0, 7) and (6, -8).
(-8 - 7) / (6 - 0) = -5/2
-5/2 is the slope
Finally, look for an equation that has 7 as the y-intercept and -5/2 as the slope.
Answer: D or answer 4
You form a rhombus.
Draw an equilateral triangle, and then mirror it around its base. All the sides are clearly equal, because they are all sides of the same equilateral triangle.
Moreover, the top and bottom angle are 60°, because they are angles of an equilateral triangle, while the left and right angles are 120, because they're 60+60 angles.
