Given:

m\angle ABC=65^\circ

m\angle BCD=105^\circ

To find:

Whether it is possible that Line AB intersects line CD​.

Solution:

We have,

m\angle ABC=65^\circ

m\angle BCD=105^\circ

The angles m\angle ABC and m\angle BCD are same sided interior angles.

If two lines are parallel and a transversal line intersect them, then the same sided interior angles are supplementary angles and their sum is 180 degrees.

m\angle ABC+m\angle BCD=65^\circ+105^\circ

m\angle ABC+m\angle BCD=170^\circ

m\angle ABC+m\angle BCD\neq 180^\circ

So, the lines AB and CD are not parallel to each other.

Therefore, the intersection of lines AB and CD is possible.

For an employee training, the employee to instructor ratio is 24 to 2. If there are 26 instructors for the training, how many em
denpristay [2]

Answer:

312 employees participated in the training

Step-by-step explanation:

Given;

employee to instructor ratio is 24 to 2

there are 26 instructors for the training

let the total number of instructors be I = 26

let the total number of employees be e = ?

employee to instructor ratio is 24 to 2, e : I = 24 : 2

e : I = 24 : 2  = e : 26

\frac{24}{2} = \frac{e}{26} \\\\e = 12 *26\\\\e = 312

Therefore, the total number of employees who participated in the training is 312

Find the solution of the system of equations. – 5 - 6y = -32 4x - 6y = 4​
amid [387]

Equation (1)

-5 - 6y = -32

Equation (2)

4x - 6y = 4

Get y alone in equation (1)

-5 - 6y = - 32\\-6y = -32 + 5\\-6y = -27\\y = \frac{-27}{-6} = \frac{9}{2}

Insert y in equation (2)

4x - 6 \cdot \frac{9}{2} = 4\\4x - 27 = 4\\4x = 4 + 27\\4x = 31\\x = \frac{31}{4}
