Answer:
You aren't supposed to add 3k
Step-by-step explanation:
3k is a positve number. So instead of adding you have to subtract to be able to move on. Correct way shown below. Once you get this step wrong your answer will also be wrong. At the end you also need to divide
19-2k= 3k-1
-3k -3k
19-5k= -1
-19 -19
-5k= -20
-5/-5= -20/-5
k=4
Answer:
B: 5/13
Step-by-step explanation:
pythagoras theorem: a^2 + b^2 (sides) = c^2 (hypotenuse)
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a = 5
sin = opp/hyp
sin 5/13
Hope this helps

Triangles cannot have two 90 degrees because that would add up to 180 and triangles need 3 angles to add to 180
You can't have an obtuse angle and a right angle. say the obtuse angle was 110, and a right angle is 90. 110 + 90 is more than 180.
Two obtuse angles would be more than 180.
This leaves us with B being correct, because you can have an obtuse angle and an acute angle, and it can be less than 180 degrees.
