Question

A surveyor took the following measurements from two irregularly shaped pieces of land. Some of the lengths and angle measurements are missing. Round lengths to the nearest tenth and angle measurements to the nearest minute.

-Find the length of a.
-Find the measurement of angle H.

Answer 1

e = 80 - 30
b = 51

Answer 2

Is the bottom right angle 25 degrees?

Answer 3

25 degrees 54 minutes is the bottom right angle

Answer 4

60 minutes = 1 degree?

Answer 5

yes

Answer 6

Ya, that's right. SO
D = 49 + 25.54 (Turn it into a decimal out of 60 for now)
D = 75.48'

Answer 7

Since it's 4 sides, all angles = 360
360 - 151.36 = 208.24
A = 208.24 / 2
Angle A = 104.12

Answer 8

what about the side a?
