Write an equation that can be used to find the degree measure of angle b

Don’t put links !

Step-by-step explanation:

Supplementary angles are angles that add up to 180. Normally, they are supplementary because they lie adjacent to one another on a line.

In this base, b is supplementary to 81! Meaning, to find b we can simply subtract 81 from 180.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

b.   e = 7.5h

hope this , lovely!
