∠DAB and ∠BAC (arc BC) are supplementary angles, angles which add up to 180°.

∠DAB + ∠BAC = 180°
26° + ∠BAC = 180°
∠BAC = 180° - 26°
∠BAC = 154°

The measure of ∠BAC (arc BC) is 154 degrees

What was the population of south Australia closest to in 2003?
Brrunno [24]
It would be 1531600

How I did it
 First I divided the percentage by 100. Example >> 0.6/100= 0.006
  Then I took 2002 population >> 1522475 +  0.006  x  1522475 = 1531609.85

a caterpillar stated at point(-2.5 -5.5) on a coordinate plane.She crawled in a straight line through the origin to point (45,y)
iren [92.7K]

Answer:

99

Step-by-step explanation:

Since the caterpillar crawled through the origin, her movement can be described by a straight line equation modeled with the points (-2.5; -5.5) and (0; 0).

The slope of a linear equation is given by:

m=\frac{y-y_0}{x-x_0}\\m=\frac{-5.5-0}{-2.5-0}\\m=2.2

For x = 45, the value of y is:

y= 2.2x\\y= 2.2*45\\y=99

The value of the y-axis is 99.
