Answer:

EITHER x = 7

OR x = 14.5

Step-by-step explanation:

When you have parallel lines and there's a third line crossing them, that makes 8 angles. 4 of these angles are ALL THE SAME MEASURE. and the other 4 angles are another number, but also ALL THE SAME MEASURE. And the two numbers add up to 180.

We kind of need to know where in the lay out of all 8 angles where are the ones you are working on. Because they are either the SAME VALUE or THEY ADD UP TO 180°

If they are the same, you set them equal to each other:

7x - 4 = 5x + 10

Subtract 5x

2x - 4 = 10

Add 4

2x = 14

Divide by 2

x = 7

OR

They add up to 180°

7x - 4 + 5x + 10 = 180

Combine like terms

12x + 6 = 180

Subtract 6

12x = 174

Divide by 12

x = 174/12 = 14.5

Answer:

HL (Hypotenuse Leg)

Step-by-step explanation:

You have BC=CD (Because of reflexive property), AC=DC, and measure of BAC is equal to the measure of BDC, which is 90 degrees. Since these triangles are right and they have a hypotenuse and a leg congruent, you can say that they are congruent because of HL.

Which of the following shows the length of the third side, in inches, of the triangle below? (1 point)
GrogVix [38]

Answer:

2, sqrt of 7633

Step-by-step explanation:

for now, we'll leave the 3rd side as x

y using the Pythagorean theorem, we can conclude that (1) 48^2+x^2=73^2 or (2) 48^2+73^2=x^2.

1. If we conclude the x isn't the longest, the x would be 3025 which is the sqrt of 55, now is invalid because the 2 smallest sides can't be more than the longest side when they add up 55+48>73 so that is invalid

2. Then, it leaves us with only 1 choice left! concluding that the 3rd side is the longest. Which the answer is sqrt of 7633
