Answer:
za=24
Step-by-step explanation:
supplementary angles add up to equal 180
180=7x+x+30+6
step 1 combine like terms
180=8x+36
step 2 subtract 36 from each side
144=8x
step 3 divide each side by 8
x=18
now we just plug in 18 to x in x+6
18+6=24
Answer:
50
Step-by-step explanation:
2(3^2+4^2)=
3^2/(3x3) = 9
4^2/(4x4) = 16
9+16=25
so.... rewritten it is
2(25)= or 2 x 25= 50
