Answer:
x = 45, y = 45
Step-by-step explanation:
AB = AD [given]
BC = DC [given]
AC = AC [common]
therefore triangle ABC = triangle ADC [SAS congruency]
therefore ∠BAC = ∠DAC [corresponding parts of congruent triangles]
x + 5 = 50 ⇒ x = 45°
also ∠BCA = ∠DCA [corresponding parts of congruent triangles]
y -7 =38 ⇒ y = 45°

Answer:
heyy friend ...first of all the question is misprint .....
the two triangles should be ABC and ACD......
that is why i m answering by taking these two triangles....
Step-by-step explanation:
( i ).... In triangles ABC & ACD....
AB = AD. ........(given in figure )
BC = CD .........( given in figure )
AC = AC ..........( common )
therefore, triangle ABC ~= triangle ACD (By SSS
criterion)
( ii ) Since, Triangle ABC =~ Triangle ACD (just prroved)
so, angle BAC = angle DAC ( by CPCT )
50⁰ = X + 5⁰
X = 50⁰ - 5⁰
X = 45⁰
Also, angle BCA = angle DCA (by CPCT )
Y- 7⁰ = 38⁰
Y = 38⁰ + 7⁰
Y = 45⁰
So here are your answes........
i hope it will help you....
