Answer:
[A] 18
Explanation:
[I'm assuming you want us to find the measure of ∠ABC]
∠ABC is a right angle, meaning ∠ABD and ∠DBC added together must equal 90°
2x° + 3x° = 90
2x + 3x = 5x
5x = 90
5x / 5 = 90 / 5
x = 18
It is not reasonable because the decimal placing on the 4.23 is greater then the one on 413. (2 is bigger then 1). When dealign with decimals it is important to remember that if the numbers before the decimal are the same for both numbers you need to look at the first decimal as though it's the first number. so we know 4 and 4 are the same. Next we look at the .23 and .13. We know that the number 2 is bigger then 1 so it's safe to say that 4.23 is larger then 4,13.
Answer:
A. congruent -SSS
Step-by-step explanation:
Picture below
Step-by-step explanation:
3×3=9. 3 faces so 9×3=27
10×3=30. 4 faces so 30×4=120
6×3=18. 2 faces so 18×2= 36
15×3=45. 3 faces so 45×3= 135
120+135=255
36+27=63
255+63=318
answer =318
