Answer:
4) 93°
5) 1°
6) 51°
7) 6°
Step-by-step explanation:
4)
180 - 36 - 51 = 93
93 °
5)
(4x + 27 ) = 180 - 64 - 85
4x + 27 = 31
x = 1
6)
theory of exterior angles in a triangle:
21 + 30 = x
x = 51
7)
3x + 42 = 46 + 44
3x + 42 = 90
3x = 48
x = 16

Answer:
Step-by-step explanation:
Thinking process:
Let the total set be the combination of all the sets as shown
It means that total items = 7 + 14 + 7 + 2
= 30
But the total number of the subsets = 5 + 7+ 2
= 14
Therefore the probability =
=
=
XZ = 40
YZ = 32
By Pythagorean Theorem,
XY = 24
sin Z = opposite / hypotenuse
sin Z = XY / XZ
sin Z = 24/40
In lowest term,
Sin Z = 3/5 (Answer)

Substitute 15 for y
Question: What is the ratio of the length of to DE the length of BC?
Answer: D, 1/5
How? Well what I did was take DE and seen how many time it could fit into BC. BC would take up a total of 5 DE's. So since we already have one which is DE then we would have 1/5.
Note: Let me know if I get it wrong. :)
