Which type of unemployment is characterized by caused by a lack of demand for workers as a result of a shrinking economy?

Cyclical Unemployment

Step-by-step explanation:

Cyclical Unemployment can further be defined as an unemployment that results when the overall demand for goods and services in an economy cannot support full employment. So, to cut of the cost of the extra workers, industries start to remove the workers and in this way the demand of the workers decreases and unemployment increases.

It occurs during periods of slow economic growth or during periods of economic contraction.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
