Answer:

$\overline{CS}\cong\overline{ST}$

Step-by-step explanation:

The congruence statement for the triangles does not list point (or angle) S, so no claim about segments or angles involving S will be supported by the congruence statement.

The statement

$\Delta BAT\cong\Delta CAT$ tells you ...

$\angle TBA\cong\angle TCA\\\angle BAT\cong\angle CAT\\\angle ATB\cong\angle ATC\\\overline{BA}\cong\overline{CA}\\\overline{AT}\cong\overline{AT}\\\overline{TB}\cong\overline{TC}$

No other claims can be made using CPCTC. The statement among the answer choices that is not true by CPCTC is ...

$\boxed{\overline{CS}\cong\overline{ST}}$

Tema [17]

Answer:

B. 5

D. 9

F. 7

Step-by-step explanation:

A triangle has sides a,b and c:

And a < b+c , b < a+c and c < b+a

Here, a = 4 and b = 7

Find c?

So, 4 < 7+c , 7 < 4+c and c < 4+7=11

A. 11 False, it doesn't satisfies inequality third

B. 5 True

C. 17 False, it doesn't satisfies inequality third

D. 9 True

E. 3 Not true it doesn't satisfies second inequality

F. 7 True

It takes 8 trees to make a stack 1.2 metres tall, so if ut takes 20 minutes per tree, then it will take 8 × 20 or 160 minutes, or 2 hours 40 minutes.
