Question

I need help with those questions plz!
​

Answer 1

Answer:

1) B=40°

•°•M=40°

because both triangles are similar so their angles will be equal

2) The ratio of areas is the square of the ratio of sides, so the ratio of the sides is sqrt(144/49)=12/7 or ratio 12:7.

3)If you need SAS congruence rule:

Then: Angle Q = Angle U

PR = SV

PQ = SU

4) AB = DE

BC = EF

AC = DF

Angle ABC = Angle DEF

Angle BAC = Angle EDF

Angle ACB = Angle DFE

Answer 2

Answer:

4:angle B=angle M (since by BPT)

therefore angle m=40 degree

5:angle PQR=angle SUV

QRP=UVS,RPQ=VSU

6:AB upon DE=BC upon EF=CA upon FD
