A triangle has six parts . . . 3 angles and 3 sides.

You've told us the value of exactly one of them . . . one of the angles ... and you've told us that the two legs of the triangle are equal.

That's not enough information to tell what any of the other parts is.

All we can tell is that the angles are 45°, 45°, and 90°, and that the third side is longer than the two equal sides.

We don't have enough information to find the length of anything. Using the given information, the base could be a millimeter, a parsec, or anything less, in between, or more. We can't tell.

X=1-2y how would you solve this?

Ivahew [28]

Answer:

You can't have a single answer.

Step-by-step explanation:

An indiviual equation can't be solved if it has 2 variables.

You can, however, graph it.

The line will create all the possible sets of answers for the problem.

Find the sum of the measures of the interior angles:

Tresset [83]

The sum of the measures of the interior angles

The sum of interior angles of any polygon can be foud wuth the following general formula

Sum of interior angles = (n-2) \ times 180^{\circ}

where n is the number of sides

1. Nonagon

The Nonagon is a polygon with 9 sides. then,

n = 9

Sum of interior angles of Nonagon

= $(9-2) \times 180^{\circ}$

= $(7) \times 180^{\circ}$

= $1260^{\circ}$

2.Pentagon

The Pentagon is a polygon with 5 sides. then,

n = 5

Sum of interior angles of Pentagon

= $(5-2) \times 180^{\circ}$

= $(3) \times 180^{\circ}$

= $540^{\circ}$

3. 11-gon

The 11-gon is a polygon with 11 sides. then,

n = 11

Sum of interior angles of 11-gon

= $(11-2) \times 180^{\circ}$

= $(9) \times 180^{\circ}$

= $1620^{\circ}$

4. 18-gon

The 18-gon is a polygon with 18 sides. then,

n = 18

Sum of interior angles of 18-gon

= $(18-2) \times 180^{\circ}$

= $(16) \times 180^{\circ}$

= $2880^{\circ}$

5. 38-gon

The 38-gon is a polygon with 38 sides. then,

n = 38

Sum of interior angles of 38-gon

= $(38-2) \times 180^{\circ}$

= $(36) \times 180^{\circ}$

= $6480^{\circ}$

6.56-gon

The 56-gon is a polygon with 56 sides. then,

n = 56

Sum of interior angles 56-gon

= $(56-2) \times 180^{\circ}$

= $(54) \times 180^{\circ}$

= $9720^{\circ}$
