Mathematics
1 answer:
Maurinko [17]3 years ago
3 0

Answer:

y = 5.6

Step-by-step explanation:

Use Sine

Sine = \frac{opposite}{hypothenuse}

Sine 45 = \frac{y}{18}

Sine of 18 is 0.309

0.309 = \frac{y}{18}

Multiply 18 on both sides

0.309 x 18 = \frac{y}{18} x 18

5.562 = y

Round to the nearest tenth:

5.562 = 5.6

Line p has a slope of -3. Line t is perpendicular to line p and passes through the point (9,2). What is the equation for line t?
olganol [36]

Answer:

y = (1/3)x - 1

Step-by-step explanation:

The product of the slopes of perpendicular lines is -1. That makes the slopes of perpendicular lines negative reciprocals. Since line p has slope -3, the slope of line t is 1/3. Also, line t passes through point (9, 2).

y = mx + b

m = slope

y = (1/3)x + b

Now we replace x and y with the x- and y-coordinates of the given point, respectively, and we solve for b.

2 = (1/3)(9) + b

2 = 3 + b

b = -1

Now we replace b with -1.

y = (1/3)x - 1
