Answer:
Second answer is the correct answer
Step-by-step explanation:
Calculate length of OA, OB and AB seperately.
There should be 2 wit the same lengths for it to be an isosceles ∆
M + f = 250 ;
m - 18 = ( 3 / 5)f ;
5m / 5 - 90 / 5 = 3f;
5m - 90 = 3f ;
5m - 3f = 90;
But, f = 250 - m;
5m - 3( 250 - m ) = 90 ;
5m - 750 + 3m = 90 ;
8m = 840;
m = 840 ÷ 8 ;
m = 105( beads for Maria );
f = 250 - 105 ;
f = 145 ( beads for Farida ) ;
Answer:
b, c e
Step-by-step explanation:
A congruence statement lists corresponding parts in the same order. CPCTC says corresponding parts are congruent.
__
To see if any particular statement is consistent with CPCTC, identify the locations of the referenced parts in the congruence statement. If they match, the congruence is true
a. l = r ... jkl = rst . . . . not in the same place
b. jk = rs ... jkl = rst . . . . a match; true
c. k = s ... jkl = rst . . . . a match; true
d. j = s ... inconsistent with (c)
e. kl = st ... jkl = rst . . . . a match; true
f. jl = rs ... inconsistent with (b)
Statements b, c, e are consistent with the congruence statement, and are true by CPCTC.
