Angle A = 68 degree

Angle B = 44 degree

Step-by-step explanation:

Sum of all interior angles = Angle A+Angle B+ Angle C

180 = 68+x+x-24

180 = 68+2x-24

180-68 = 2x-24

112+24 = 2x

136/2 = x

68 = x

Therfore, Angle A = 68 degree

Angle B = (x-24)

= (68-24)

= 44 degree

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
