Question

answer plzzz allll and make it clear

Answer 1

11-a.....2m+2n=180, linear pair
=====
m+n=90

(b). n=30
m+30=90
m=60

(c). aoc=m+n=90

bod=90
coe=90

(12).
(a). d and b
a and c

(b). (d, b), (a, c)., (b, d), (c, a)

(c). (a, d), (a, b), (b, c), (c, d)

(d) 180-a=180-100=80

(e) a=105=c

a+d=180

d=75=b

(13).90-56=34
90-38=52

(14).
(a) 90-60=30
(b). abc:: 180-60=120
y::: 180-90=90

(c) since 90+60 is not equal to 180...
hence angles are not supplementary

(d). no.. as 90+60 is not equal to 180

(15).let the angles be a and 2a/3
a+2a/3=180
5a=180*3
a=36*3=108

(16).6x=180
x=30

(b). 4x+20=7x+5
-3x=-15
x=5

(c)not visible but it will be solved as first part... linear pair that is sum =180

(d). 10x=360
x=36
