To find a reasonable estimate using decimal numbers, round the decimal to the nearest whole number, so for example 3.4 x 7.5 You can round 3.4 and 7.5 what would the the answer be? I need help answer please

The answer after rounding is 24

Step-by-step explanation:

You would round down 3.4 to 3 and round up 7.5 to 8

3 x 8 = 24

The actual answer of 3.4 x 7.5 is 25.5, so 24 isn't too far off.

Since , the figure is a rhombus. This implies that opposite angles are congruent. In particular, we have angle A is congruent to angle C.

So, triangle ADB and triangle CDB have two sides in common (AD=CD and AB=BC), and the angle between those side in common (angle A=angle C).

So, by the SAS criterion, they are congruent.
