need help with math please?
1.in triangle PQR, PQ is extended through Q to point T, forming exterior <RQT.if m<RQT=70 and m<R=10,find m<P
2.AB intersects CD at e; m<AEC=2x=10;m<AED=3x-30
b.show that AB is perpindicular to CD

m<p = 60 degrees
Do you mean m<AEC = 2x-10? or 2x+10? regardless, you could solve it this way:
If you know that AB and CD are perpendicular, then 3x-30=90 degrees. solve for x, you find that x=40 degrees.
