<span>Let opposite ray be drawn for the base side ray of the given angle.
This gives angle 180° between these two rays.
Angle bisectors of the given angles 50°, 90°, and 150° make respectively half of these angles : 25° , 45° and 75° with the base ray.
Then measure of the angles between the bisectors of the given angles and the drawn opposite ray are 180°-25°=155°, 180°- 45° =135° and 180°- 75° = 105° respectively.</span>
        
             
        
        
        
Answer:
-3 1/8.
Step-by-step explanation:
 −7/8 − 2 1/4
= -7/8 + -9/4 
= -7/8 - 18/8
= -25/8
= -3 1/8.
 
        
             
        
        
        
Answer:
3/100
Step-by-step explanation:
convert these measurements into one unit, I am going to do decimals but you can sue fractions or percentages as well.
1/4 is 0.25
2/5 is 0.4
0.12 is 0.12
20% is 0.2
if you add all these up, it equals 0.97
1- 0.97= 0.03
you therefore have 0.03 of the money left over
this as a fraction is 3/100
 
        
             
        
        
        

Answer : No, the new type of letter wouldn't be considered as a success because its response rate (2.71%) is lower than the average response rate which is 4%.
Hope this helps. - M
