Special right triangles, find x and y

egoroff_w [7]

Answer:

The answer to your question is x = 17.32; y = 8.67

Step-by-step explanation:

Process

1.- Use trigonometric functions to find x and y

a) sin Ф = $\frac{opposite side}{hypotenuse}$

Ф = 60°

opposite side = 15

hypotenuse = ?

$hypotenuse = \frac{opposite side}{sin \alpha }$

$hypotenuse = \frac{15}{sin 60}$

$hypotenuse = \frac{15}{0.87}$

hypotenuse = 17.32

b) cosФ = $\frac{y}{hypotenuse}$

$y = hypotenuse x cos 60$

$y = 17.32 x 0.5$

y = 8.67

Hi GlaxyCraft4991,

Solution:

−12x − 0.4 > 0.2 (36.5x + 80) − 55

−12x − 0.4 > 7.3x − 39

−12x − 0.4 − 7.3x > 7.3x − 39 − 7.3x

−19.3x − 0.4 > −39

−19.3x − 0.4 + 0.4 > −39 + 0.4

−19.3x > −38.6

−19.3x/19.3 > −38.6/19.3

x < 2

Correct Answer:

x < 2

A tractor trailer weighs 80,000 pounds. Two tractor trailers come upon a bridge with a sign saying it can only handle 100 tons.

NikAS [45]

Two tractor trailers would weigh 160,000 pounds, which is equal to 80 tons. 100-80= 20 tons that are still available.
