Answer:
3.1
Step-by-step explanation:
sine 70= x/4
sin= opposite/hypotenuse
Answer:
B and D
Step-by-step explanation:
Equations with the same x- term on both sides will have no solution
A
4x - 13 = 5(x + 4) = 5x + 20
4x ≠ 5x
This equation has a solution
B
5(3 + 2x) = 10x + 4
15 + 10x = 10x + 4
10x on both sides ⇒ no solution
C
2(3 - 5x) = 8(x + 1)
6 - 10x = 8x + 8
- 10x ≠ 8x
This equation has a solution
D
9x - 6 = 3(3x - 2) = 9x - 6
9x on both sides ⇒ no solution
28.96
or rounded it would be 29
Answer:
Z equals 16. Hope this helps!
Hi there!
It depends on what angles there are, and how many degrees are in each angle. In order to figure this problem out, you need to know at least one angle ;)
Hope this helps!
