The answer to number 27

vovikov84 [41]

Area = Length x width.

30 = w x 3w +1

Simplify:

3w^2 + w = 30

Subtract 30 from both sides:

3w^2 + w -30 =0

Factor

(w-3)(3w+10) = 0

Solve for the w's:

w = 3 and x = -3 1/3

Since the number cant be negative w = 3

The width = 3 cm.

In triangle abc, angle A is the right angle. What is the value of y?

Natalka [10]

Answer:

Step-by-step explanation:

In a right triangle, the side opposite to the 90 degree angle (here, side opposite to angle A) is known as the hypotenuse.

Also, the side that is "opposite" to the angle given (here side opposite is y to angle given 30 degrees) is the opposite side.

Since we want to find "opposite" and have "hypotenuse" , recalling trig ratios, we can say opposite/hypotenuse is the ratio SINE, so we can write:

$Sin(30)=\frac{y}{7}$

We solve for y:

$Sin(30)=\frac{y}{7}\\y = 7 Sin(30)$

Since the answer choice has angles in radians, we recall 30 degrees is $\frac{\pi}{6}$ radians.

Thus, the correct answer is $7Sin(\frac{\pi}{6})$ , or option A
