I believe you would use tan since you are using an opposite side and an adjacent side

tan(60°) = L/20 m

tan(60°) = 1.732

1.732*20 = 34.64

Also, this triangle is a 30, 60, 90 triangle (see attached image) in which 20 m = a. 20*√3 = 34.64.

I hope this helps!! :)

Write a phrase $3 more than four times the cost of a pretzel as an algebraic expession

olasank [31]

Answer:

$4x+3$

Step-by-step explanation:

Let

x ----> the cost of a pretzel

we know that

The phrase" $3 more than four times the cost of a pretzel" is equal to multiply the cost of a pretzel x by 4 and adds the number 3

The algebraic expression is

$4x+3$

In △QRS, QR = 7, RS = 11, and m∠R = 42. In △UVT, VT = 28, TU = 44 and m∠T = 42. Are the polygons similar? If they are, write a s

deff fn [24]

Since we are going to check the similarity of the triangles and we have given two sides and angle we have to check the Side-Angle-Side option of the similarity. We have equal angles. Then, we have to check the proportionality of the sides. If these triangles are equal, then VT/QR=UT/RS. If we calculate it, 28/7=44/11=4. This last number is the similarity ratio and since we have proportionality, ΔQRS <span>~ </span>ΔVTU. The correct answer is D)

Consider the reduction of the rectangle

Alexandra [31]

The question is incomplete. The complete question is as follows.

Consider the reduction of the rectangle. A large rectangle has a length of 16.8 feet and width of 2.3 feet. A smaller rectangle has a length of 4.5 feet and width of x feet. Not drawn to scale (The drawing is in the attachment). Rounded to the nearest tenth.

What is the value of x?

A. 0.1 feet

B. 0.6 feet

C. 1.6 feet

D. 2.0 feet

Answer: B. 0.6 feet

Step-by-step explanation: Two quantity are proportional if the ratio of them is constant. From the drawing and the question, we have that the two rectangles are proportional between them.

$\frac{x}{2.3} = \frac{4.5}{16.8}$
