Answer:
Jeez this is a big question
Step-by-step explanation:
1. if they are rounded to the nearest 10 that would mean that it is actually
40 * 40
40 * 40 is 1600. The answer for #1 is 1600
2. its just asking what 21 x3 is, 21x3 is 63
3. All you do for this is 20*23
20 * 23 is 460
4. 42 * 31 is 1302
5. 22 * 95 = 2090
6. You do 20x2 which is 40 and then you do 8x2 which is 16
Adding
then you have 40 + 16 = 56
Subtracting
40 - 16 = 24
Multiplying
40 * 16 = 640
Dividing
40/16 = 2.5
7. 33x2 is 66
8. 57* 4 is 228
9. 128 * 11 is 1408 but if you round the 11 to the nearest 10, that would be 10, then if you round the 128 to the nearest 10, that would be 130, and then 130 * 10 is 1300
No the congruence statements are sas,asa,sss, aas and hl

Step-by-step explanation:
Answer:
the answer is a. 147
Explaination:
A triangle always has a sum of 180°.
We already have the angle of two sides give.
10° and 23°
To find the last missing side, you add 10° and 23°, and minus the result from 180°.
10+23= 33
180-33 = 147
