∠ 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:

Step 1: Define Systems

y = -7x + 6

y = -10x

Step 2: Solve for x

Substitution

Substitute in y: -10x = -7x + 6
Add 10x to both sides: 0 = 3x + 6
Isolate x term: -6 = 3x
Isolate x: -2 = x
Rewrite: x = -2

Step 3: Solve for y

Define equation: y = -10x
Substitute in x: y = -10(-2)
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!
