Step-by-step explanation:

(2c + 8) + (6c - 6) = 90 \\ 8c + 2 = 90 \\ 8c = 88 \\ c =  \frac{88}{8}  = 11

The figure will equal to 90 degrees.

So what you want to do is this:

1. Add them both, and equal

2. Add like terms,

and equal that

to 90 degrees.

3. Then minus 2

from both sides.

4. And you will 88 on the

right side, and 8c on the

left side.

5. Just divide from both sides.

2c+8+6c-6=90

8c+2=90

-2 -2

8c=88

/8 /8

c=11

Consider isosceles ΔXYZ.

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The length of the legs XY and YZ is equal to 39 units.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°. An isosceles triangle has two sides out of three equal.

A.) The value of n can be found by equating XY and XZ together,

XY = XZ

9n + 12 = 15n - 6

12 + 6 = 15n - 9n

18 = 6n

n = 3

Hence, the value of n is 3.

The length of different legs of the triangle is,

B.) XY = 9n + 12 = 9(3) + 12 = 27 + 12 = 39

C.) YZ = 15n - 6 = 15(3) - 6 = 45 - 6 = 39

Hence, the length of the legs XY and YZ is equal to 39 units.

What is the area? Bit confused on this one.
DENIUS [597]

Answer:

x² + 8x + 12

Step-by-step explanation:

see

the length of the entire rectangle = x + 6

breadth of the entire rectangle = x + 2

area of a rectangle = length × breadth

= (x + 6)(x + 2)

= x² + 8x + 12

which is the required polynomial in standard form
