3x-5=2x
2x-3x=-x
-5=-x
-5/-1=5
-x/-1=x
5=x
2×5=10
BC is 10 units
(-4b - 8) = 20
-4b = 20 + 8
-4b = 28
b = -7
If this is a true or false statement then it is true
Answer:
Correct options,
a)
c) and ∠A = ∠X
Step-by-step explanation:
Given : ΔABC ≅ Δ XYZ
We have choose out of given options that correctly prove that ΔABC ≅ Δ XYZ
Two triangles are said to be similar when their corresponding sides are in same ratio and the measure of their corresponding angles are equal.
That is
and ∠ A = ∠X , ∠ B = ∠Y AND ∠C = ∠Z
Also ,
We have conditions for two triangle to be similar.
1) SSS : When the ratio of all the three sides of a triangle are equal.
that is
2) SAS: When the ratio of two corresponding sides are equal and the measure of angle between those sides are equal
and ∠ A = ∠X
Thus, Out of given options,
a)
c) and ∠A = ∠X
