Answer:

A) True

Step-by-step explanation:

A basic variable is a variable that corresponds to a pivot column. A variable that does not corresponds to a pivot column is known as a free variable. It is required to row reduce the augmented matrix into echelon form so as to determine which of the variables are free and which of them are basic.

Find the measure of the missing angles.<br> 62°<br> b\co
tiny-mole [99]

The measures of angles B and C are 118° and 62°, respectively.

<h3>What are the measures of two missing angles generated by the intersection of two lines?</h3>

A system of three angles is generated by two lines intersecting each other. In accordance with Euclidean geometry, angle C is opposite to the angle with measure 62° and angle B is supplementary to the same angle.

When two angles are opposite, then both have the same measure, and when two angles are supplementary, then the sum of their measures equals 180°. Therefore, the measures of angles B and C are 118° and 62°, respectively.

Ex plane how knowing 50 x 4 = 200 helps you find 500 x 400
Alex777 [14]

Answer:

Step-by-step explanation:

if you know 50*4=200, you must also know that 50*10=500 and that 4*100=400 so 500*400= 50*10*4*100

multiplication is comutative so

50*4*10*100=200*1,000= 200, 000

The measure of angle KMJ??
Irina18 [472]
44

Assuming JM and LN are parallel, KMJ=MKN. MKN is part of a triangle where the other two values are defined (48 and 88). By subtracting these values from 180, we find the value of MKN is 44, which therefore is also the value of KMJ.
