Answer: x = 21 degrees

Step-by-step explanation: Angle BCA is equal to angle x.

159 + x = 180 (add like terms)

x = 21 (subtract 159 from both sides)

2. State whether the change is increasing or decreasing. Round your percent of change to the nearest integer percent. originally
marysya [2.9K]

Answer:

The change is increasing with a percentage of change of 64%

Step-by-step explanation:

Since we have the present grater than the original, then the change is increasing

Secondly, we want to calculate the percent of change

Mathematically , that will be ;

(present - original)/original * 100%

= (90-55)/55 * 100%

= 35/55 * 100% = 63.63 which is approximately 64%
