Answer:
65
Step-by-step explanation:
the sum of interior angles in a triangle equal to 180°
so 45+70=115
180-115=65

Answer:
241°
Step-by-step explanation:
You are given the triangle internal angle (N) at Naples = 46°, and the side opposite a = 765 km. You are given the side b = 515 km, and asked to find an angle related to the internal angle opposite (C).
By the law of sines, the internal angle (C) at Canton is ...
sin(C)/b = sin(N)/a
C = arcsin((b/a)sin(N)) = arcsin(515/765·sin(46°)) ≈ 28.964°
The bearing from Elgin to Canton will be 270° less this angle, so is about 241°.

Comment on your answer
Apparently, you added 29° to 270°, rather than subtracting. Since the direction from Elgin to Canton is south of west, the bearing angle must be between 180° and 270°. Note that a line west from Elgin will be parallel to the line east from Canton, so you can take advantage of alternate interior angles being congruent where the Elgin-Canton line crosses those parallel east-west lines.

Answer:
A, E
Step-by-step explanation:
Wanted expression: 6(b+2)-b
Let's factorise each expression and make it look like the wanted expression as much as possible.
A: 5b+12
<em>In this case we do not have a "-b" at the back, to make it similar to the given expression we can insert a "-b" at the back while adding 1 b to the front (5b) of the expression.</em>
6b+12-b
6(b+2)-b
B: 7b+8
8b+8-b
8(b+1)-b
C: 6b+8-b
2(3b+4)-b
D: 5b+8
6b+8-b
2(3b+4)-b
E: 6b+12-b
6(b+2)-b
The 2 expressions out of A-E that are the same as the wanted expression are A and E.
hope this helps :))
