Answer:
15.) 104 ... I hope angles are not drawn to scale
16.) 144
17.) 37
Step-by-step explanation:
15.)
3x + 10 = 4x -12
22 = x
so 3x +10 = 76
180 - 76 = t = 104
16.)
2(21) + 36 + 90 + bcd + a = 360
a = 90 - 21 = 69
360 - (2(21) + 36 + 90 + 69) = bcd
bcd = 360 - 237 = 123
angle acd = 21 + bcd = 21 + 123 = 144
17.)
(5x - 7) + 90 + (3x + 1) = 180
8x -6 = 90
8x = 96
x = 12
so 5x - 7 = 53
90 - 53 = angle lmn = 37
Answer:
Midsegment=1.7
Step-by-step explanation:
Distance formula
d = √(x2 - x1)^2 + (y2-y1)^2}
d=√(4-(-2)^2+(3-4)^2
simplify and solve
we find d=1
Now side lenght
d=√((-2-(-2))^2+(4-(-2))
d=2.44949
length of midsegment=1/2 x (2.44949+1)
1.724745
simplifies to
1.7
Method 1
10% - 43 |multiply both sides by 10
100% - 430
Answer: 43 is 10% of 430.
Method 2
10% - 43
100% - x
/cross multiply/
10x = 100·43
10x = 4300 |divide both sides by 10
x = 430
Answer: 43 is 10% of 430.
$14.52 because $20 - $5.48 = 14.52
Steph = x + 5
Klay = x
Andre = x - 4
I will set it up and you finish.
Here is the equation you need:
x + 5 + x + x - 4 = 55
Can you finish on your own?
