Answer:
Let's solve for x.
4x+2y=345x−6y
Step 1: Add -345x to both sides.
4x+2y+−345x=345x−6y+−345x
−341x+2y=−6y
Step 2: Add -2y to both sides.
−341x+2y+−2y=−6y+−2y
−341x=−8y
Step 3: Divide both sides by -341.
−341x
−341
=
−8y
−341
x=
8
341
y

Answer:
decagon has total 1440° interior angles.
Explanation:
using the formula to find total interior angle: ( n -2 ) * 180
<em>where n is the number of sides</em>
<em>Here given the number of sides is 10</em>
<em>using the formula:</em>
( 10 - 2 ) * 180
1440°
Answer:
9/2and 5/2 is correct answer
Answer:
Step-by-step explanation:
Given:
ΔCAD and ΔCBD
∠A ≅∠B (Angle)
AD ≅BD (Side)
From the graph we see that
CD≅CD (Side)
because of reflexive propriety ( a line segment is congruent with itself)
If you put in order those congruencies we have SSA witch does NOT prove congruence.
we not use SAS because the angle between the sides is not congruent
It can be any angle between 1 and 64 since the third angle has to be a right angle or an obtuse angle
