Angle a and angle b are complementary angles. if angle a measures 40 degrees, what is the measure of angle b? *
40 degrees
45 degrees
50 degrees
140 degrees

50 degrees

Step-by-step explanation:

we know that

If two angles are complementary, then their sum is equal to 90 degrees

so

A+B=90°

we have

A=40°

substitute and solve for B

40°+B=90°

B=90°-40°=50°

c

step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
