x=y and y=x is the same and y=-x is the same as x=-y bro this is grade 5 things....

but while doing transformation stuffs hw can we know in reflection ???

Refer to similarity
Ration of corresponding sides =7/10
Ration of areas= 49/100 or (7/10)2
Are of triangle PQX= (49/100)* Area of SRX
PQX= (49/100)* 20
=9.8
And for the next one are of a triangle =1/2ah
20=1/2*10*h
20*2=10*h
40/10=h
4=h
Hope it helped

okay use the formula prt/100= amount extra received after simple interest
you knw Marcus got 415 for his C.I
400*r*2/100= 415-400
800*r=15*100
r=5.125
got it

you see there are 6 triangles in so yo know are of triangle=1/2*a*b*sinc <----this is for 1 triangle for you multiply by 6
and a and b will be 2.5 and 2.5 as it is a regular hexagon and all triangles inside will be equal side
