Answer:

No because one is bigger than the other and the smaller one has a 90 degree angle and the big one has a 60 and 70 degree angle

Answer:

No, they are not similar

Step-by-step explanation:

The three triangle angles should always add up to 180 degrees.

In the smaller triangle, one angle is 90 degrees, so the other 2 angles in that triangle will equal 90 when added.

In the bigger triangle, the 2 other angles are 60 & 70 degrees, amounting to 130 degrees. This means the last angle will be 50 degrees.

In the end, these two triangle are <u><em>NOT similar</em></u> because one has a right angle and the other doesn't.

n airplane took off from an airport and traveled at a constant rate and angle of elevation. When the airplane reached an altitud

hram777 [196]

The angle of the plane when it rose from the ground is 64.8 degrees

<h3>Application of trigonometry identity</h3>

Given the following parameters from the question

Altitude of the airplane H = 500m

Horizontal distance from airport "d" = 235

Required

angle of elevation

According to the trigonometry identity

tan x = opposite/adjacent

tan x = H/d
tan x = 500/235

tan x = 2.1277

x = arctan(2.1277)

x = 64.8 degrees

The angle of the plane when it rose from the ground is 64.8 degrees

The equation

ra1l [238]

<h2>Explanation:</h2>

Let's use a trial and improvement method to find this solution.

Step 1. Let's choose x = 8.5

Substituting into the equation:

$(8.5)^2+ 3(8.5) - 94=0? \\ \\ 72.25+25.5-94=0? \\ \\ 3.75\neq 0$

Step 2. Let's choose x = 8.4

Substituting into the equation:

$(8.4)^2+ 3(8.4) - 94=0? \\ \\ 70.56+25.2-94=0? \\ \\ 1.76\neq 0$

Step 3. Let's choose x = 8.3

Substituting into the equation:

$(8.3)^2+ 3(8.3) - 94=0? \\ \\ 68.89+24.9-94=0? \\ \\ -0.21\neq 0$

Since the sign of the equation changes from positive to negative when evaluating from 8.4 to 8.3, then x = 8.3 seems to be a reasonable value. Finally, the solution to 1 decimal place is:

$x=8.3$

Vincent needs 20 inches of wood to makeOne shelf. How many feet of wood does Vincent need to make 6 shelves

butalik [34]

Answer:

10 feet

Step-by-step explanation:

Multiply 20 by 6 which will give the answer 120 (in inches).
Then convert 120(inches) to feet by dividing with 12.
The answer will be 10(feet) needed for six shelves.

20x6= 120

120/12=10

=10 ft

In an effort to learn more about the wild lemur population in Madagascar, a researcher wants to collect a sample. Which statemen

steposvetlana [31]

A reseacher wants to collect a sample to learn more about the wild lemur population in Madagascar. According to this, the true statement is the reseacher can assign each lemur a number and then use a systematic sampling (option A).

Systematic sampling is a form of sampling characterized by choosing the sample at random. According to the above, random sampling is the best option for the researcher.

It is not easy to study the entire population of lemurs in Madagascar, therefore systematic sampling is ideal. In this way, the researcher can sample a few lemurs and using this probability method can draw conclusions.

According to the above, the correct answer is A. because it presents information corresponding to the situation presented.
