Answer:
The correct option is;
d) CPCTC
Step-by-step explanation:
The phrase Corresponding Parts of Congruent Triangles are Congruent with the acronym CPCTC, is used as valid reasoning in the provision of a proof, after the existence of congruency between two triangles has been proven
Given that the triangles ΔDOG and ΔCAT have been proven congruent, we have that the corresponding vertices are;
Vertex D corresponds to vertex C
Vertex O corresponds to vertex A
Vertex G corresponds to vertex T
Therefore, given that ΔDOG ≅ ΔCAT, we have;
∠D ≅ ∠C by CPCTC
∠O ≅ ∠A by CPCTC
∠G ≅ ∠T by CPCTC.
Answer:
x = 50°
Step-by-step explanation:
the sum of the exterior angles of any polygon is 360°
2x-12 + 32 + 2x + x + 90 = 360
5x + 110 = 360
5x = 250
x = 50
Answer:
1,4,6
Step-by-step explanation:
To find out if something is a function try the vertical line test. This means you should be able to draw a vertical line anywhere on the graph and it will only intersect with the graph once. A function is a relation in which each input has only one output. The graphs 1,4,6 all pass the vertical line test while the others do not.
Answer:
7x-7 or -49
16x2 is 32, minus the 81 is negative 49 (-49)
