Sum of angles in a triangle is 180°:
180 - 50 - 62 = 68
Sum of angles in a triangle is 180°:
180 - 80 - 53 = 47
Sum of angles in a triangle is 180° / Vertically opposite:
180 - 68 - 47 = 65°
Answer: 65°
Answer:
5/3
Step-by-step explanation:
In this question, we are trying to find the slope of the line with the given points.
To find the slope, we would use the slope equation: m = y2-y1/x2-x1
Plug in the coordinates and solve:
-5 - 5/-3 - 3
-10/-6
Simplify further while canceling out the negative.
5/3
The slope of the line would be 5/3
Answer:
117
Step-by-step explanation:
6/8 x/156 so 156/8=19.5*6=117

Answer:
5/13
Step-by-step explanation:
According to SOH CAH TOA
cos theta = adj/hyp = -12/13
Get the opposite using pythagoras theorem
13^2 = (-12)^2 + opp^2
169 = 144 + opp^2
opp^2 = 169-144
opp^2 = 25
opp = 5
Get sin θ
sin θ = opp/hyp
sin θ = 5/13
hence the value of sin θ is 5/13
