1 answer:
ryzh [129]2 years ago
6 0

Answer:

C

Step-by-step explanation:

3x+4x-19+3x-1=180

10x=180+19

x = 199/10 = 19 (round to 20)

x = 20

<A= 20

<B= 80-19= 61

<C=. 59

The longest side is across from the largest angle. Draw the triangle ABC.

AC is across <C (the largest angle)

This is the result of solving an equation to find a value(s) for the variable(s) which make the equation true.
SOVA2 [1]

Answer:

Step 1: Simplify both sides of the equation.

8−2(3−x)=4x+6

8+(−2)(3)+(−2)(−x)=4x+6(Distribute)

8+−6+2x=4x+6

(2x)+(8+−6)=4x+6(Combine Like Terms)

2x+2=4x+6

2x+2=4x+6

Step 2: Subtract 4x from both sides.

2x+2−4x=4x+6−4x

−2x+2=6

Step 3: Subtract 2 from both sides.

−2x+2−2=6−2

−2x=4

Step 4: Divide both sides by -2.

−2x

−2

=

4

−2

Explain how to use the Pythagorean Theorem to find the missing length of a right triangle.<br>​
tino4ka555 [31]

Pythagorean theorem.

a^2+b^2=c^2

This means that the square of the length of the 2 legs of a right triangle added together = the square of the length of the hypotenuses or diagonal.

If you know 2 of the values in the 3 variables a,b,c what would you do to find the missing variable value?

I will not write the exact answers to this problem. I think you can figure how to write it out yourselves.
