Answer:
x= 35
Step-by-step explanation:
Cos x = Sin( 20+x)
Sin ( 90 – x) = Sin(20+x)
90 – x = 20+x
2x = 70
x = 35
Answer:
A rational number is a number that can be express as the ratio of two integers.
Step-by-step explanation:
A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever).
Answer:
y = x - 14
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 1, thus
y = x + c ← is the partial equation of the line
To find c substitute (14, 0) into the partial equation
0 = 14 + c ⇒ c = 0 - 14 = - 14
y = x - 14 ← equation in slope- intercept form
