ANSWER
EXPLANATION
The given expression is
We multiply out to obtain,
Recall that,
We apply this rule to obtain,
This simplifies to
The answer is 45°
By determining the angles of triangle ACB (A=30°, B=45°, C=105° (total of 180°)) and knowing that angle 1 correlates to angle 4 ((1)°=(4)°), we can find angle 1, which is 45°, equal to angle 4.
Answer:
c = 154°

Answer:
-4
Step-by-step explanation:
We know it's a linear equation and the slope is a whole number. Using point slope form we will write the equation:
y - y1 = m (x - x1) in which y1 is -7, m is 3, and x1 is -1
y - (-7) = 3(x-(-1))
y+7 = 3(x+1)
y+7 = 3x +3
Change to slope-intercept form:
y = 3x + 3 - 7
y = 3x = -4
the y intercept is -4
Answer: x=-2+2 sqrt 6 divided by 5
