Answer:
y = -x -1
Step-by-step explanation:
x1= 0, y1= -1
-1 = x/(y+1)
-1 (y+1) = x
y+1 = -x
y= -x -1
Keep in mind that:
- the sum of the interior angles of every triangle in existence is 180 degrees
- the base angles of isosceles triangles are congruent
With this information, I have created a diagram. I encourage you to always draw a diagram when you can - it aids in the solving process.
Now, to find <em>a</em>, set the measures of the interior angles equal to 180.
(<em>a</em> + 15) + 7<em>a</em> + 7<em>a</em> = 180
Solve for <em>a</em>.
<em>a</em> + 15 + 7<em>a</em> + 7<em>a</em> = 180
15 + 15<em>a</em> = 180
15<em>a</em> = 165
<em>a</em> = 11
Find the angle measures by plugging 11 for <em>a</em>.
<em>a</em> + 15
(11) + 15
26
7<em>a</em>
7(11)
77
Check your work by adding the angles measures.
77 + 77 + 26 = 180
<h3>
Answer:</h3>
<em>a</em> = 11
Each base angle measures 77 degrees and the vertex angle measures 26 degrees.
Answer:
y≤46
it's the third one. hope it helps
Answer:
B. Metric measurements are based on powers of 10; customary measurements are not.
Step-by-step explanation:
Multiply both sides by 10.
5v - 4 = 8
Add 4 to both sides.
5v = 12
Divide both sides by 5 to find v.
v = 12/5
