Too easy
remember all angles in traingle add to 180
straight lnes are 180
so
35+59+x=triangle
35+59+x=180
x=86
x+y=line
x+z=180
86+z=180
z=94
11+z+y=triangle
11+94+y=180
y=75
x=86
y=75
z=94
yah, 2nd one
Answer:
Y = -0.09594X + 74.35629
Step-by-step explanation:
Given the data :
Job average annual salary (X) :
81
96
70
70
70
92
92
100
98
102
Stress tolerance (Y) :
69
62
67.5
71.3
63.3
69.5
62.8
65.5
60.1
69
Using technology, the linear model Obtian by fitting the given data is :
Y = -0.09594X + 74.35629 ;
Where ;
Y = stress tolerance (dependent variable)
X= Average annual salary (Independent variable)
Slope = 0.09594
Intercept = 74.35629
Answer:
(x) =
Step-by-step explanation:
Given
y = x + 5
Rearrange making x the subject
Multiply through by 3 to clear the fraction
3y = 2x + 15 ( subtract 15 from both sides )
3y - 15 = 2x ( divide both sides by 2 )
= x
Replace x by (x) and y by x, thus
(x) =
The angle 86 makes the tan 14.3
