What is mzA? Enter your answer as only a number

A = 25

B = 65

Step-by-step explanation:

Remark

I hope you mean what is the size of <A? If not leave a note. If I am correct than A and C are complementary (equal 90o) since B is a right angle.

Solution

2x + 1 + 5x + 5= 90            Combine like terms

7x + 6 = 90                         Subtract 6 from both sides

7x = 90-6

7x = 84                               Divide by 7

x = 84/7

x = 12

Now that is not quite the answer.

A = 2x + 1

A = 2*12 + 1

A  = 25

B = 5x + 5

B = 5*12 + 5

B = 60 + 5

B = 65

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
