Answer:
<h3> A: One</h3><h3> B: x = 4 </h3>
Step-by-step explanation:
3(2x - 7) = 3
÷3 ÷3
2x - 7 = 1
+7 +7
2x = 8
÷2 ÷2
x = 4
Answer:
hello its (1/4)x+4=3
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
Answer + Step-by-step explanation:
1) D be the symmetric of B with respect to C then CD = BC
A the symmetric of C with respect to B then AB = BC
We obtain :
CD = BC
AB = BC
Then AB = CD
2) m∠SBA = 180 - SBC = 180 - SCB = m∠SCD
3) we have :
BA = CD
BS = CS
m∠SBA = m∠SCD
Then
the triangles SBA and SCD are congruent
4)
the triangles SBA and SCD are congruent Then SA = SD
Therefore SAD is an isosceles triangle.
