Answer:

Step-by-step explanation:
Scalene triangle are the triangle with no side are equal in length also each angle have different measure.
As given there are two scalene triangle, which are similar.
∴ Side of both the triangle will be propotionally equal.
Scale is given for both the triangle, which is 5:2.
We know, scale factor= ratio of the side.
Looking the option provided, we see 
As the sides of both the triangle is propotionally equal
Hence,
.
135 + (-136) = 135 - 136
= -1
126 + (-747) = -621
-1 - (-621) = -1 + 621 = 620

A - 36 = B
B = 76 - A * 2.
the number is 40.
A = 40

Answer:
SN =
= 7
Step-by-step explanation:
SN² + 24² = 25²
SN² + 576 = 625
SN² = 49
SN =
