Answer:negative two
Step-by-step explanation:
Given:

To find:
The congruent angles and sides, then find the another valid congruency statement.
Solution:
We have,

We know that, corresponding parts of congruent triangles are congruent (CPCTC).
Using CPCTC, we get
Angles:



Sides:



The another congruent statement is
.
Therefore, the required table is

Answer:
x = 4
Step-by-step explanation:
The measures of all angles in this geometry are 90 degrees.
21x +6 = 90
21x = 84 . . . . . subtract 6
x = 4 . . . . . . . divide by 21
Answer:
x=1
Step-by-step explanation:
3(4x+1)=15
12x+3=15
12x=15-3
12x=12
x=12/12
x=1
