Option B. 55° is the correct answer
Step-by-step explanation:
"The sum of interior angles of a triangle is always 180°"
Given
m∠A=(3x+1)°
m∠B=(2x-1)°
m∠C = 40°
We know that
m∠A+m∠B+m∠C=180°
Putting the values of angles

Subtracting 40 from both sides

Dividing both sides by 5

We have to find Angle B,
So
m∠B = 2x-1 = 2(28)-1 = 56-1 = 55°
Hence,
m∠B=55°
Option B. 55° is the correct answer

Answer:
Step-by-step explanation:
9 + 4 = 13 Two minus' make a plus
14-9 = 5     this is just subtraction
-4 + 5 = 1   two minus's make a plus.
-7-9 = -16
 
        
             
        
        
        
Yes
The rule to check if a triplet of numbers can represent the sides of a triangle is the following: the sum of the length of two sides must exceed the third one.
This happens for all possible couples in your case:
