Find the value of x
14x-15 and 139 degrees (look at the image)

x=4

Step-by-step explanation:

Simplifying

(14x + -15) + 139 = 180

Reorder the terms:

(-15 + 14x) + 139 = 180

Remove parenthesis around (-15 + 14x)

-15 + 14x + 139 = 180

Reorder the terms:

-15 + 139 + 14x = 180

Combine like terms: -15 + 139 = 124

124 + 14x = 180

Solving

124 + 14x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-124' to each side of the equation.

124 + -124 + 14x = 180 + -124

Combine like terms: 124 + -124 = 0

0 + 14x = 180 + -124

14x = 180 + -124

Combine like terms: 180 + -124 = 56

14x = 56

Divide each side by '14'.

x = 4

Simplifying

x = 4

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
