if three angles are complementary, then they all ad up to 90 degrees. if the third angle is 10 degrees, then there are multiple answers for the other angles. one could be 35 degrees and 45 degrees.

Answer:

The first angles is 40

The second angle is  40

The third angles is  10

P.S I put this in a random order.

You could do this too

The first angle is  10

The Second angles is 40

The third angle is 40

The oder does not matter but the numbers do

Step-by-step explanation:

So complementary angles add up to 90 Degrees. SO if 2 angles are the same and the third angle is 10. Then subtract 90-10 which is 80. Then divide it by 2 because 2 angles have the same length. 80/2 is 40. So the measurement of the other angles is 40 degrees.

Which could be the resulting equation when elimination is used to solve the given system of equations ?
WINSTONCH [101]

Answer:

10·b = 60

Step-by-step explanation:

The given system of equation is presented as follows;

5·a + 5·b = 25...(1)

-5·a + 5·b = 35...(2)

Given that the coefficient of a in equation (1) is equal in magnitude but opposite in sign to the coefficient of 'a' in equation (2), to eliminate the variable 'a' when using the elimination method, we add both equations as follows;

5·a + 5·b + (-5·a + 5·b) = 25 + 35 = 60

5·a - 5·a + 5·b + 5·b = 60

5·a - 5·a = 0

5·b + 5·b = 10·b

∴ 5·a - 5·a + 5·b + 5·b = 60 = 0 + 10·b = 10·b

∴ 10·b = 60

Find the value of X <br><br> PLEASE
Oliga [24]

Answer:

x ≈ 18

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Trigonometry</u>

Law of Cosines: a^2 = b^2 + c^2 - 2(b)(c)cosA

  • a is a side length
  • b is a side length
  • c is a side length
  • A is an angle corresponding with side a

Step-by-step explanation:

<u>Step 1: Define</u>

a = x

A = 30°

b = 16

c = 30

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute:                    x² = 16² + 30² - 2(16)(30)cos30°
  2. Exponents:                   x² = 256 + 900 -2(16)(30)cos30°
  3. Evaluate:                       x² = 256 + 900 -2(16)(30)(√3/2)
  4. Multiply:                        x² = 256 + 900 - 480√3
  5. Add:                              x² = 1156 - 480√3
  6. Subtract:                       x² = 324.616
  7. Isolate <em>x</em>:                       x = √324.616
  8. Evaluate:                       x = 18.0171
  9. Round:                          x ≈ 18
