Step-by-step explanation:

making m the subject first by dividing through by 4


from the question, given n = -1 ,0 ,1
so when n= -1


when n=0



when n=1


 
        
             
        
        
        
30°
A strait line is 180°
75°+75°=150°
180°-150°=30°
        
             
        
        
        
Answer:
Remember the formula for calculating volume is: Volume = Area by height. V = A X h.
For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.
So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.

Answer:
m∠8 = 49°
Step-by-step explanation:
∠7 and ∠8 are same-side interior angles.
Remember, same-side interior angles are supplementary. This means that the sum of the angles is 180°.
Let's use the variable 'x' to represent the unknown measure of angle ∠8.

 (cancels itself out)
 (cancels itself out)


Therefore, the measure of ∠8 is 49°.
