Question

Look at the two triangular flags below.



What is the length of the side BC of triangle ABC?

8 cm

26 cm

5 cm

32 cm

Answer 1

Whoever helps Ill give a medal promise :)

Answer 2

First let us prove that the two triangles are congruent.
<BAC=<FDE
AC=DF
<ABC+<DEF
Therefore the two triangles are congruent by ASA.
Nw since they are congruent
BC=EF
3x+2=4x-6
2+6=4x-3x
x=8
So BC=3*8+2=24+2=26
Is it clear?

Answer 3

Omg got it thankssss so much!!

Answer 4

U r welcome.:)

Answer 5

wanna help more ? :D

Answer 6

sure.

Answer 7

Look at the two triangular sign boards below.



Which pair of equations is correct?

x = 70 and y = 55

x = 3 and y = 65

x = 4 and y = 4

x = 4 and y = 50

Answer 8

Here too the triangles are congruent.
so
y+5=55
y=55-5
y=50
15x+10=70
15x=70-10
15x=60
x=60/15
x=4

Answer 9

is it clear?
