Answer:
25%
Step-by-step explanation:
120/480=0.25
Answer:
Slope= -4
Step-by-step explanation:
Slope is rise over run (y over x)
So, looking at the table, you can see that every time the y values went down by 8, the x values went up by 2.
So, the slope can be written as:
-8/2
Simplified to -4/1 or just -4
Answer:
Option (4)
Step-by-step explanation:
By applying triangle sum theorem in ΔABC,
m∠A + m∠B + m∠C = 180°
80° + 40° + m∠C = 180°
m∠C = 180° - 120°
m∠C = 60°
Since, ∠ACB ≅ ∠DCE [Vertically opposite angles]
m∠DCE = m∠ACB = 60°
Now by applying triangle sum theorem in ΔCDE,
m∠DCE + m∠CED + m∠CED = 180°
60° + 70° + x° = 180°
x = 180 - 130
x = 50°
Therefore, Option (4) will be the answer.
Answer:
T1= -7;
T2= -6;
T3= -3
Step-by-step explanation:
T1=1^2-2x1-6= -7;
T2=2^2-2x2-6= -6;
T3=3^2-2X3-6= -3.
Answer:
D. m = 20 , n = 10.
Step-by-step explanation:
The sine of 60 is √3/2, so
sin 60 = 10√3 / m = √3/2
√3 m = 20 √3
Divide both sides by √3:
m = 20.
cos 60 = 1/2 = n / 20
2n = 20
so n = 10.
