Shane's Textbook Post Pages 103-105. Numbers 7,10,13,15

a.)

h² + g² = r²
h² + 5² = 9²
h² = 9² - 5²
h² = (9x9) - (5x5)
= 81-25 = 56
= h² = 56 mm²
= h = 7.48 mm
b.)

p² + q² = r²
p² + 11² = 15²
p² = 15² - 11²p
p² = (15x15) - (11x11)

= 225 - 121 = 104
= p² = 104 mm²
= 10.20

a² + b² = c²
27 m² +
27 m² = c²

(27x27) + (27x27)
729 + 729 = c
²

1458 m²
1458 m² =
38.18 m²

a² + b² = c²
8² + b² = 10 mm
b² = 10² - 8²
b² = (10x10) - (8x8)
= 100 - 64 = 36
= b² = 36 mm²
= b = 6 mm

a² + b² = c²
=22 + 42 = c²
=4 + 16 = c²
=20 = c²
The square root of 20 = c²

c² = 4.47

1. Great job Shane. I love your pictures and the questions were answered perfectly. I love that you changed the colour of the answers, it looks great.

2. I really liked the pictures you've picked, but next time add a video or a link to catch your audiences' attention.
