Answer:
Area (A) = ½ (b × h) square units
Step-by-step explanation:
The general formula for calculating the area of a triangle is; Area (A) = ½ (b × h) square units, where; A is the area, b is the base, and h is the triangle's height. The triangles might be different in nature, but it important to note that this formula applies to all the triangles.
B, D represent pairs of vertical angles.
___
Other pairs may be congruent, but they are not vertical angles. The lines that look parallel must be assumed to be NOT parallel, because they are not marked in the diagram as being parallel. Thus ∠8 ≠ ∠12, for example.
The answer is A. (-5,2) . also i suggest you using photomath if you have a trouble with a problem it will give you the answer and the steps to solve
Answer:
12/2=6
Step-by-step explanation:
You have to do the same thing to each side and try and move all the numbers to one side, leaving x alone so:
2x-5=7
+5:
2x=12
/2:
x=12/2
x=6
Answer:
-7/18
Step-by-step explanation:
[-1/5 - (-2/3)] • (-5/6)
=[-1/5 + 2/3] • (-5/6)
=[7/15] • (-5/6)
=7/15 * -5/6
=-7/18
