16x+2+26y=180 (corresponding angles)
45x-5+16x+2=180 (consecutive interior)

16x+26y=180-2
45x+16x=180-2+5

16x+26y=178
61x=183 (divide by 61 both sides of the equation) --> x=3

when x=3, then 16x+26y=178 is
16×3+26y=178 (subtract 48 (48=16×3) from both sides of the equation)
26y=130 (divide both sides of the equation by 26)

y=5

answer: x=3 and y=5

144+64= 178

$\sqrt{178 } = 13.3$

a^2+b^2= c^2

Whenever finding a missing length use the formula up above :

a^2+b^2= c^2

a^2-b^2= c^2

144-64= 80

$\sqrt{80} = \sqrt{16 } \times \sqrt{5} = 4 \sqrt{5} = 8.9$

Answers are 13.3 and 8.9
