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

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
