Answer:
What is the questions here? if you want area the answer is 3.
Step-by-step explanation:
Answer:
3) B) 90°
4) A) 75°
Step-by-step explanation:
3) interior angles of a triangle =180°
So
40+50+?=180
? =180- 90
? =90
4) same rule
40+65+?=180
? =180 - 105
? = 75
Answer:
A
Step-by-step explanation:
The consecutive values of 
have a common difference d, that is
d = 8 - 3 = 13 - 8 = 18 - 13 = 23 - 18 = 5
This indicates that the sequence is arithmetic.
The recursive formula allows the next term in the sequence to be found from the previous term by adding 5, thus
= 
+ 5 → A
1. V = lwh
V = (8)(4)(5)
V = (32)(5)
V = 160 units³
2. V = lwh + lwh
V = (4)(2)(1) + (3)(1)(1)
V = (8)(1) + (3)(1)
V = 8 + 3
V = 11 units³
3. V = leh + s³
V = (9)(3)(4) + (3)³
V = (27)(4) + 27
V = 108 + 27
V = 135 units³
4. V = lwh
V = (3)(7)(2)
V = (21)(2)
V = 42 units³
