Ireally need on this im bad at math anyway but i cant see graphs clearly first good answer will get brainliest
in abc below, what is the measure of angle b? in particular, which option below gives an exact expression for m band an approximation that is correct to the nearest tenth of a degree? note: the triangle is not drawn to scale.

Exact value,  

Approximation,  

Step-by-step explanation:

In ΔABC, ∠C=90°

We are given a right angle triangle.

Side AB is hypotenuse = 4

Side AC is one leg = 3

Using trigonometry identity:

The exact value of

The approximation of

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.

hope to and hope that my answer is brainliest.(follow me )

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 : )
