Question

pls answer the 5 of them

Answer 1

Answer:

your answer is

Linear pair

Answer 2

I)2 obtuse angle (angle more than 90⁰)

ii)4 in rectangle and 1 out side=5

iii) angle x=sum of opposite sides of∆

x=110⁰+30⁰

x=140⁰,

y=

y+x=180⁰(supplementary to each other)

y+140=180

y=180-140

y=40⁰

z=

y+z=90⁰(both are completery to each other)

40+z=90⁰

z=90-40

z=50

iv) angle y ratio angle z

y:z

40:50

4:5

v) some of opposite both opposite angles of∆=exterior angles
