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: The length is 48 and the width is 32. The area of the larger shape is 1536.
When the size increase by a factor of 4, we multiply all the values by for.
12 x 4 = 48
8 x 4 = 32
Our new values are 48 and 32.
Now, multiply those to find the new area. 48 x 32 = 1536.
