Answer:
No.
There's no congruence theorem or statement that proves that 2 triangles with 2 sides and a non-included angle are congruent to each other.
Step-by-step explanation:
The triangles given, ∆ABC and ∆CYZ both have a non-included angle and two sides given that are congruent to each other.
However, this alone is not enough to prove that both ∆s are congruent to each other because there is also possiblity of another ∆ that will have the same two equal sides and a non-included angle as any of the 2, and can thereby have different shape and size.
There's also no congruency statement that proves that two triangles with congruent two sides and a non-included angle are congruent to each other.
Therefore, the information to us is not enough.
Answer: 114
Step-by-step explanation:
Let the number be y
35% of y = 40
35/100 × y = 40
35y/40 = 100
Cross multiply
35y = 100×40
35y= 4000
y= 4000/35
y= 114.29
The number is 114.29
