Answer:
115°
Step-by-step explanation:
A triangle always has 3 angles, and thew sum of the angles is always 180°. Therefore,
38° + 27° + x° = 180°
65° + x° = 180°
x° = 115°
X1= -3 -root 29 /2
x2=-3+ root 29 /2
Answer:
C
Step-by-step explanation:
idk it just sounds like a conditional probability to me.
It’s 8n-12 because it’s trying to find the difference so you would replace the and with the subtraction sign
Answer:
see below
Step-by-step explanation:
1) see attached image
2) <u> bearings from A to B</u>
Note: bearing is always clockwise from A and from North.
(i)
bearing 180° + 67°
247° from N
(ii)
bearing 148 + 180
328° from N
(iii)
bearing 180 - 21
159° from N
(iv)
39° from N
(v)
bearing 90 - 40
50° from N
3) <u>back bearing from each diagram on no. 2</u>
<u />
Note: subtract 200 if bearing is more than 180
add 180 if the bearing is less than 180
(i) 247 - 200 = 47°
(ii) 328 - 200 = 128°
(iii) 159 + 180 = 339°
(iv) 39 + 180 = 219°
(v) 50 + 180 = 230°
