Answer:

{\huge{\pink{\underline{\underline{Solution:}}}}}

As we know,sum of angles on a straight line is 180 degree..

(5z-4)+90+39=180

=>5z-4+90+39=180

=>5z-4+129=180

=>5z+125=180

=>5z=180-125

=>z=55÷5

Hence,the value of z=11 degree

Which gives the correct values for points A, B, C, and D?
saveliy_v [14]

Answer:

<em>The correct answer is: A</em>

Step-by-step explanation:

<u>Points on a Numeric Line</u>

The numeric line shown in the figure has four points A, B, C, and D. It's clear that each marked division of the line has a value of 1/4 units and all four points are below the reference zero, thus all are negative.

Point A is clearly on the -2 mark, thus

A=-2

Point B is one mark above A, thus it's located at:

B=-2+\frac{1}{4}=-\frac{7}{4}=-1\frac{3}{4}

B=-1\frac{3}{4}

Point C is one mark below -1, thus:

C=-1-\frac{1}{4}=-1\frac{1}{4}

Finally, point D is one mark below 0:

D=-\frac{1}{4}

The correct answer is: A
