In ∆MKP and ∆MNP

MK = MN

PK = NP

MP = MP

SO ∆MKP AND ∆MNP ARE CONGRUENT.

SO m<PMN = m<PMK


m<NMK = 50

=> m<PMN + m<PMK = 50

=> 2 m<PMK = 50

=> m<PMK = 50/2 = 25°

the ages of John and Mary total 27 years. Mary's age plus twice john's age is 40. how old is each person?
son4ous [18]
So
Jon's age=j
mary age=m


m+j=27
m+2 times j=40
m+2j=40
M+j=27
ssubtract j from both sides
m=27-j
subsitute 27-j for m
27-j+2j=40
27+j=40
subtract 27 fromboth sdies
j=13

subsitue
13+m=27
subtract 13
m=14

mary=14
john=13
