Answer:
102 degrees.
Step-by-step explanation:
Because the 3.3's are congruent (the same), this triangle is isosceles.
A property of isosceles means that the two angles are congruent.
39+39= 78
This means that the last angle must be 180-78.
Answer:
x = 4
Step-by-step explanation:
Step 1: Combine like terms
9x + 6 = 42
Step 2: Isolate x by subtracting 6 on both sides
9x = 36
Step 3: Isolate x by dividing by 9 on both sides
x = 4
Answer:
- 1.375
Step-by-step explanation:
Each dot is worth -1/8 of a unit when moving left.
So the coordinates of the dark dot are - 1 and - 3/8
or - 1.375 . The word coordinates (plural) bothers me. It all depends on how you have been asked to represent these points. Another possibility is (-1.375,0). You have to choose from the examples you have been given. I wouldn't do that because you have not been given and xy graph.
Answer:
<h3>
A'(-2,0) , B'(0.5,6) and C'(3,0)</h3>
Step-by-step explanation:
The vertices of triangle ABC are A(−5, 1), B(−2.5, 7), and C(0, 1).
The given translation of vertices,
<h3>
(x, y) → (x + 3, y − 1)</h3>
This translation shows shift x-coordinate 3 unit right and y-coordinate 1 unit down.
- First translate vertices A(-5,1)
New vertices A'(-2,0)
New vertices B'(0.5,6)
New vertices C'(3,0)
Hence, the new coordinate of the vertices are A'(-2,0) , B'(0.5,6) and C'(3,0)
