Answer: B. A triangle with sides measuring 50 mm 35 mm and a non-included angle measuring 25° .

Step-by-step explanation:

A. A triangle with sides measuring 5 inches, 7 inches, 9 inches

Only one triangle can be possible because all the triangles with equal sides must be equal by SSS congruence rule.

B. A triangle with sides measuring 50 mm ,35 mm and a non-included angle measuring 25°.

More than one triangle can be possible because there is no congruence rule for two equal sides and one non-equal angle ( no SSA rule exist).

C. A triangle with sides measuring 5 cm, 10 cm, and 15 cm .

This triangle is not possible because it doesn't satisfy triangle's inequality as 5+10=15  [Triangles inequality : a+b> c, where a, b, c are sides of triangle]

D. A triangle with sides measuring 8 cm and 12 cm in an included angle measuring 85°.

Only one triangle can be possible because all the triangles have two equal sides and their included angle is equal by SAS congruence rule.

Hence, the required measurement to create more than one triangle:

A triangle with sides measuring 50 mm 35 mm and a non-included angle measuring 25° .

So, correct option is B.

Can someone plz help?

Answer:

<em>x = 12 in ; Type in 12 in the box</em>

Step-by-step explanation:

If we were to apply triangle formula ; 1/2 * base * height, we would see that length of height ⇒ 10 inches, and length of base ⇒ x inches,

Given an Area of 60 square inches let us substitute into the formula 1/2 * base * height and solve for x;

Area of Triangle = 1/2 * base * height,

60 in^2 = 1/2 * x in * 10 in ⇒ take 1/2 * 10,

60 in^2 = 5 in * x in ⇒ divide either side by 5 in,

12 in = x in ⇒ divide either side by inches,

x = 12 inches,

<em>Solution; x = 12 in</em>

Please help and hurry please

Answer:

Add 4 positive unit tiles to each side.

Step-by-step explanation:

The original equation is:

3x - 4 = 2x + 5

After adding 4 positive unit tiles to each side, we get:

3x - 4 + 4 = 2x + 5 + 4

3x = 2x + 9

which simplifies the original equation, because at the beginning there were independent terms at both sides of the equal sign and now all independent terms are on the right side (the +9 term). Notice that the other options don't give this result.

20x+3=17 help please
jeyben [28]
The objective is to get the variable (x) alone. To do this start be subtracting 3. What you do to one side you have to do to the other so you have to subtract three from the other side of the equal sign as well. So now you have:
20x= 17-3 subtract the 3 to get 20x=14
Now because the 20 is attached to the x In order to get the x alone you have to divide by 20:
20x/20. =14/20 divide 14 by 20

X=.7 or x=7/10
