A square have all its four sides equal and at right angles.
Let the side of first square be 'a'
and the side of second square be 'b'
Given:
equation:1
equation:2
Solving equation:1
a=10+b equation:3
Putting 'a' in equation:2

Putting 'b' in equation:3

So, the side of first square is 14 units and

Answer:
1. (B) 73
2. r = 15
Step-by-step explanation:
1. The sum of angles in a triangle is 180°.
62° +45° +k° = 180
k = 180 -107
k = 73
__
2. The sum of exterior angles of any polygon is 360°.
4r° +7r° +5r° +8r° = 360°
24r = 360 . . . . . . . . . . . . . collect terms, divide by °
r = 360/24 . . . . . divide by 24
r = 15
(y2-y1)/(x2-x1)
(-7-5)/(4-2)
-12/2= -6
