Set up the equation:
x=(3x-70)
0=2x-70
2x=70
x=35
Now to find LMN we plug it back in:
3(35)-70=35
Final answer: 35 degrees

Answer:

Step-by-step explanation:
Using cosine (since that is adjacent over hypotenuse), cos(60)=1/2 so your answer is hypotenuse*1/2=
Step-by-step explanation:
So the way you do this is if it says 'Find AC' and on the angle you see different letters connect then on the lines and name the angle
More that 90°= Obtuse
90° angle= 90° angle
Less than a 90° angle= isosolines angle
Answer:
area=144
Step-by-step explanation:
so we need to find the length of each side
since its a square there is 4 sides
perimeter is all the sides added up
48/4=12
the formula for a squares are is b*h
12*12= 144
