Answer:

Option B.

Step-by-step explanation:

It is given that two sides of a triangle each measure 8 inches. Maria says the triangle must be isosceles.

We need to check whether Maria is correct or not.

Isosceles triangle: If a triangle has at least two sides that have equal measures, then the triangle is called an isosceles triangle.

Since measures of two sides of the triangle are equal, therefore the given triangle is an isoseceles triangle and Maria is correct.

Hence, the correct option is B.

I need help, this is geometry

Artemon [7]

Answer:

∠P = 39º

∠Q=120º

∠R = 21º

Step-by-step explanation:

m∠P+m∠Q+m∠R=180º (sum of ∠s in a triangle)

2x-3+6x-6+x=180º (substitution)

9x-9=180º (algebra)

9x=189º (algebra)

x=21º (algebra) (this is ∠R)

(2x-3)=39º (algebra) (this is ∠P)

6x-6=120º (algebra) (this is ∠Q)

Hi! I'm Jenny and I'm a mathematician! I'd love to help you with this problem! :)

Lets get started...

I'll write the equation out for you!

x + x(xx)

Put the value of x = 2 in the above expression we get,

2 + 2(22)

= 2 + 2(2 × 2)

= 2 + 2(4)

= 2 + 8

= 10

Write an equation in Standard Form using the correct properties. Convert this equation to Slope-Intercept Form.

Lubov Fominskaja [6]

Answer:

I think what you are asking for is an example.

Step-by-step explanation:

Standard form equation

8x-4y = 20

1. move 8x to the other side

-4y=20-8x

2. divide both sides by -4

$\frac{-4y}{-4} = \frac{20-8x}{-4}$

3. Solve for this...

y=2x-5

7. Isosceles triangle ABC is shown below with legs that measure 8 inches and a vertex angle of 50D. (a) Determine the area of AB

Flura [38]

Answer:

<h2>The area of the triangle ABC is 32 square inches.</h2>

Step-by-step explanation:

We know that the given triangle is a right-isosceles triangle, which means its leg are equal.

The area of a triangle is defined as

$A=\frac{1}{2}bh$

Where $b=8$ and $h=8$ . Replacing values, we have

$A=\frac{1}{2} \times 8 \times 8 = 32 \ in^{2}$

Therefore, the area of the triangle ABC is 32 square inches.
