Select the correct answer. The sum of two complementary angles is 90°. For one pair of complementary angles, the measure of the first angle is 15 less than twice the
measure of the second angle. Write system of equations that can be used to determine the measure of the first d, angle, a, and the measure of
the second angle, b.

A. a+b=90, 2b-15=a

B. a+b=90, 2b+15=a

C. a+b=90, a-2b=15

D. a+b=90, 2a-15=b

A

Step-by-step explanation:

The first angle (a) is 15 less than twice the second angle (b)

So, twice the second angle is 15 more than the first:

2b = a+15

Simplify:

2b - 15 = a

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
