2 trig ratios missing sides and angels

Mathematics
1 answer:
ivanzaharov [21]3 years ago
8 0

Answer:

D

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos66° = \frac{adjacent}{hypotenuse} = \frac{13}{x} ( multiply both sides by x )

x × cos66° = 13 ( divide both sides by cos66° )

x = \frac{13}{cos66} ≈ 32.0 ( to the nearest tenth )

What are the X- and y- intercepts of the line? 2x + 3y = -12
Lera25 [3.4K]
Subtract 2x from both sides. 

3y = - 2x - 12

Divide every term by 3 to get the y-variable by itself.

y = - 2/3x - 4

Since the equation is not in slope-intercept form (y = mx + b), your y-intercept is just the number in the b slot. Y-intercept is - 4 or (0, - 4).

Now to find your x-intercept, plug in 0 where the y-variable is and solve for x.

0 = - 2/3x - 4
4 = - 2/3x 

Multiply both sides by - 3/2 to isolate the variable. 

4(- 3/2) = x
- 12/2 = x
- 6 = x.

Your x-intercept is - 6 or (- 6, 0).

Reduction of 12
3 x 4 = 12

Increase of 10
5 x 2 = 10

75 - 12 = 63
63 + 10 = 73

Change = 2 inches (75 - 73)
