Answer:
1/2
Step-by-step explanation:
So do this, think of an equilateral triangle. A 30-60-90 triangle is just half of an equilateral triangle. If the original side length was x, then the hypotenuse is x, one leg is x/2, and the third, by Pythagorean theorem, is x sqrt3
Sin is opposite over hypotenuse, so we have (x/2)/x = 1/2
Answer:
$658
Step-by-step explanation:
42 x 99 = 4,158
4,158 - 3,500 = 658
This involvea factoring the polynomial into binomials and solving.
So make it (3x+1)(x-7)
X equals 7 and -1/3
Answer:
B. Line B

Undefined slopes are when x equals a certain number.
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
From the given choices, B is the correct answer.
A has a slope of 0, so <em>m</em> = 0 and would become a horizontal line.
C has a negative slope, so it is not undefined.
D has a positive slope, so it is not undefined.
B shows a vertical line, and so it has an undefined slope.
