The perfect whole squares are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100.
Less than 30 are:
<h2>1, 4, 9, 16, 25</h2>
First picture
ABC is a triangle so
m<A +m<B+m<C = 180
6x - 1 + 20 + x + 14 = 180
7x + 33 = 180
7x = 180 - 33
7x = 147
x = 147/7
x = 21
m<A = 6x - 1 = 6(21) - 1 = 125
m<C = x + 14 = 21 + 14 = 35
answer:
m<A = 125
m<C = 35
-----------------------------------------
second picture
ABC is a triangle so
m<A +m<B+m<C = 180
48 + 6x - 28 + 2x = 180
8x + 20 = 180
8x = 180 -20
8x = 160
x = 160/8
x = 20
m<B = 6x - 28 = 6(20) - 28 = 120 - 28 = 92
m<C = 2x = 2(20) = 40
answer:
x = 20
m<B = 92
m<C = 40
