Unit 4 Lesson 7 Honors GeoB

1: Obtuse

2:16√2ft

3: 13√2 in

4: x=12;y=4√3

5: 67.11 degrees

6: 197.5 meters

7: 154ft

8: 405 meters

9: 139ft

10: 125.1in^2

11: 6

12: 27.8 in

13: 35 degrees

14: 48.6 degrees

15: 34 degrees

Answer 2

We know that angle A is 90 degrees, and angle B is 45 degrees, which means angle C is also 45 degrees. That tells us that BA and CA are equal in length.

a^2 + b^2 = c^2
16^2 + 16^2 = c^2
512 = c^2
sqrt(512) = c
c = 16 sqrt(2)

The answer is B
