Answer:

Perimeter of triangle CDE = 56

Step-by-step explanation:

Here, we want to find the perimeter of CDE

mathematically, when the measure of the inner triangle is half of the respective sides of the bigger

What this mean is that for each side that one of the side of the inner triangle faces, the measure on the bigger triangle is twice

Thus, 9 represents a length of 2(9) = 18 on the bigger triangle

Also, 7 will represent a length of 2(7) = 14 on the bigger triangle

So, now we have the complete sides of the bigger triangle

The measure of the perimeter is simply the addition of the respective side lengths

We have the perimeter of the large triangle as;

24 + 18 + 14 = 56

Two interior angles of a scalene triangle measure 85 and 50 degrees. The third angle measures:

zmey [24]

The interior of a triangle = 180°
So 180° - 85° -50° = 45°

c. 45 degrees

Solve the problem. Find the amount of money in an account after 12 years if $4700 is deposited at 5% annual interest compounded

Dmitrij [34]

Answer:

The correct answer is $8532.17

Step-by-step explanation:

The formula for calculating investments with compound interests is as follows:

$(1+\frac{R}{t})^{tn}*P$

Where:

R is the annual interest rate,

t is the number of times the investment is to be compounded in a year,

n is the number of years,

P is the principal amount invested.

Replacing in the formula with the given values you have:

$(1+\frac{0.05}{4})^{4*12}*4700 = 8532.1678$

The missing angle of the right triangle ABC has a measure of 30°. (Correct answer: A)

<h3>How to find a missing angle by triangle properties</h3>

Triangles are geometrical figures formed by three sides and whose sum of internal angles equals 180°. There are two kind of triangles existing in this question: (i) Right triangles, (ii) Isosceles triangles.

Right triangles are triangles which one of its angles equals 90° and isosceles triangles are triangles which two of its sides have equal measures.

According to the statement, we know that triangle BQR is an isosceles triangle, whereas triangles ABC, ANB and NBC are right triangles. Based on the figure attached below, we have the following system of linear equations based on right triangles ABC and NBC:

2 · x + 90 + θ = 180 (1)

(90 - x) + 90 + θ = 180 (2)

By equalizing (1) and (2) we solve the system for x:

2 · x = 90 - x

3 · x = 90

x = 30

And by (1) we solve the system for θ:

θ = 180 - 2 · x - 90

θ = 30

The missing angle of the right triangle ABC has a measure of 30°. (Correct answer: A) $\blacksquare$
