The measure of angle a is 40° wrote an equation that will you determine the measure of angle b

50 degrees

Step-by-step explanation:

You know it's a right angle, so that means it is 90 degrees, just subtract 40 degrees from 90 since you know a = 40 and a+b=90

90 (degrees) - a = b

90 (degrees) - (40) = 50 (degrees)

Step-by-step explanation:

The little box in the corner indicates that it is a right angle, all right angles are equal to 90 degrees.

They gave you the value of (a) and we know that (b) must be equal to 90 degrees when added to (a).

Subtract 90 from 40 and that gives you fifty degrees.

the thermometer is precise but not accurate

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
