Answer:
BC =21.03540021
Step-by-step explanation:
We know the measure of angle B since the sum of the angles of a triangle add to 180
A + B+ C = 180
61+ B + 12 =180
B = 180 - 12 -61
B =107
Then we can use the law of sines to find BC
sin B sin A
-------- = -------------
AC BC
sin 107 sin 61
-------- = -------------
23 BC
Using cross products
BC sin 107 = 23 sin 61
BC = 23 sin 61/ sin 107
BC =21.03540021
Answer:
(C.) AC¯¯¯¯¯≅EG¯¯¯¯¯ is true
Step-by-step explanation:
The positions of the letters in naming the triangles in the statement of congruent tells you which sides are congruent.
△ABC≅△EFG
Sides AB and EF are congruent
△ABC≅△EFG
Sides BC and FG are congruent
△ABC≅△EFG
Sides AC and EG are congruent
Look at the choices:
(C.) AC¯¯¯¯¯≅EG¯¯¯¯¯ is true
7 because if its between 7.1 and 7.4 itll round to 7 and if it between 7.5 and 7.9 it would be 8. therefore the answer is 7

Looks like all you have to do it multiply the numbers together; there is no application of the Distributive Property to these problems.
