Answer:
see explanation
Step-by-step explanation:
Since the triangles are similar then the ratio of corresponding sides are equal
(a)
= 
, substitute values
= 
( cross- multiply )
13.23AB = 111.132 ( divide both sides by 13.23 )
AB = 8.4
(b)
= 
, substitute values
= 
( cross- multiply )
6.3DF = 54.243 ( divide both sides by 6.3 )
DF = 8.61
Answer:14
Step-by-step explanation:First, you can plug in the numbers, so the equation would look like 126=1/2b(18). Since theres 1/2, 1/2 of 18 is 9, so it would be 126=9b. 126/9=14
Answer:
10-4 and (8-5)2
Step-by-step explanation:
10-4=6 and 8-5=3 3×2=6
For A you should put -3 and for b put 2
Answer:B because you multiply all the similar numbers together then at the end you add them all up.
