Answer:
Step-by-step explanation:
Given:
ΔCAD and ΔCBD
∠A ≅∠B (Angle)
AD ≅BD (Side)
From the graph we see that
CD≅CD (Side)
because of reflexive propriety ( a line segment is congruent with itself)
If you put in order those congruencies we have SSA witch does NOT prove congruence.
we not use SAS because the angle between the sides is not congruent
Answer:
The shape has a total area of 14.96cm²
Step-by-step explanation:
To solve this all you need to do is take the area of the outer rectangle, and subtract the area of the inner rectangle.
The outer rectangle is 5.6 by 6.4 cm. To get its area, just multiply those dimensions. When you do so you get the area 35.84cm².
Next the inner rectangle needs to be subtracted. First though, we need its width, which we're not directly given.
We do however know the width of the entire shape, and the width of segments left after cutting out the inner rectangle. All we need to do then is subtract the later from the former to the the inner rectangle's width:
5.6cm - 1.2cm - 0.8cm = 3.6cm
Great! The inner rectangle has an area of 3.6cm × 5.8cm. That gives us 20.88cm².
The final step is to subtract that 20.88 square cm from the 35.84 that we already have. Doing so gives us a result of 14.96cm², and that is the final answer.
Answer:
I think the answer is 73.
Step-by-step explanation:
did it state the volume?
wait its a right angle, so its 90 degrees?
the answer would be -1,224 because the parentheses is your multiplication and the it is a negative
