Aand b are complementary angles. the measure of a is twice the measure of b. me and !

A = 60

B = 30

Step-by-step explanation:

Complementary angles add to 90 degrees

A = 2B            A is twice the measure of B

A + B =90    Complementary angles add to 90 degrees

Substitute the first equation in for the second

A+B =90

2B+B=90

Combine like terms

3B = 90

Divide by 3

3B/3 = 90/3

B = 30

A = 2B

A = 2*30

A = 60

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

y = i/2 xtnop + (3i/2 tnop+ 1)
