Please help me with this question.

The measurement of largest angle is 83°

Step-by-step explanation:

Given angles are:

(2x+1)° , (x+15)° and x°

The sum of internal angles of a triangle is 180°

We will use this sum to find the value of x first

Now the measurement of angles are:

x = 41

Hence,

The measurement of largest angle is 83°

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3
