∠ A = 32° , ∠ A = 55°, THEN ∠ C = (180° - 32° - 55°) = 93°

This triangle having an angle > 90° is then an OBTUSE TRIANGLE

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = -7x + 6

y = -10x

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

<em>Substitution</em>

  1. Substitute in <em>y</em>:                   -10x = -7x + 6
  2. Add 10x to both sides:      0 = 3x + 6
  3. Isolate <em>x</em> term:                    -6 = 3x
  4. Isolate <em>x</em>:                             -2 = x
  5. Rewrite:                              x = -2

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                    y = -10x
  2. Substitute in <em>x</em>:                       y = -10(-2)
  3. Multiply:                                  y = 20

3m + 8 + m = 36 which can be substituted for m to make this equation true?
PilotLPTM [1.2K]

Answer:

m = 7

Step-by-step explanation:

3m + 8 + m = 36 , that is

4m + 8 = 36 ( subtract 8 from both sides )

4m = 28 ( divide both sides by 4 )

m = 7

Please help me with my math ty
Alja [10]
Hello!

You can use the Pythagorean Theorem to solve this 

a^{2} + b^{2} = c^{2}

c is the hypotenuse which is the side across the right angle
a and b are the other sides

Put in the values you know

9^{2} + 12^{2} = c^{2}

Square the numbers

81 + 144 =  c^{2}

Add

225 =  c^{2}

Take the square root of both sides

15 = c

The answer is 15

Hope this helps!
