We know that the total is 180 degrees of the lines.
To find x:
(5x+20)+(4x-11) = 180
x=19
To find y, input the value of x into the equation 4x-11 since this equation is equal to 2y+19
4(19)-11 = 65
2y+19 = 65
y=23
1. x - (-16) = -13
x= -3
2. n = -425------- n=-85 5
3. x + 6 < 15 x <9
4. x + (5-2) > 7 x >5
5. m < --- _ 48 m< 5 12
6. 5m > 45 m>8
7. 3x +4 < 37 x<10
Answer:
B. 8/5.
Step-by-step explanation:
We find this by dividing the lengths of the corresponding sides.
Scale factor = 40 / 25
= 8/5.
Answer:
Step-by-step explanation:
Given:
To find 
Using trigonometric relations for sums and differences of squares of the ratios.
We know:
Plugging in in the above relation.
Subtracting both sides by 0.75.
Taking square root both sides.
∴ (Answer)
