Answer:
66
Step-by-step explanation:
Angle 2 and 4 are supplementary, so if angle 4 is 123, then 180-123=57.
So angle 2 is 57.
Then, if angle 2 and 3 are 57 and we know that all angles of a triangle have to add up to 180, then:
57+57+angle 1=180
114+ angle 1=180
angle 1= 66

Answer:
Today's temperature is 5.7 degrees above Bill's normal temperature.
Step-by-step explanation:
Given
Represent the normal temperature with N and today's temperature with T.
Such that:


Required
Determine the temperature above the normal temperature
The interpretation of this is to calculate the difference between Bill's normal temperature and Bill's today temperature.
Represent the difference with D
D is calculated as follows:

Substitute values for T and N


Hence, today's temperature is 5.7 degrees above Bill's normal temperature.
