Answer 1

Answer:

50°

Explanation:

180°-(65°+65°) =180°-130°=50°

Answer 2

Answer:

25

Explanation:

so let the given angle 65 be x

and angle beside it be angle i

and angle which we have to find be angle r

so

x + i = 90 as normal ray is prependicular

65 + i = 90

i = 90 - 65

i = 25

as

angle i is equal to angle r

i = r

so r = 25
