a) ABD and CBD are Supplementary angles and need to equal 180 degrees

Subtract 117 from 180 for CBD:

CBD = 180 - 117 = 63 degrees

b) In triangles the the shortest side would be opposite the shortest angle.

Since angle D is 56 degrees ( the smallest inside angle) then side BC would be the shortest side.

c) The side opposite the largest angle would be the longest.

Angle B is 63 degrees ( the largest) so side CD is the longest.

The Third Side Is Called The base if an isosceles triangle has perimeter 345 cm and base length 85 cm what is the length of each

maks197457 [2]

Answer:

Length of each leg = 130 cm.

Step-by-step explanation:

Given that there is an isosceles triangle which has perimeter 345 cm.

Base length =85 cm.

Since other two sides are equal, let the equal size = x

Perimeter = sum of all 3 sides of a triangle

= 85+x+x = 85+2x

But perimeter = 345 (given)

So equate x term perimeter with actual

85+2x = 345

Subtract 85

2x = 260

Divide by 2

x =130 cm.

Hence answer is 130 cm.

Factor the polynomial.

Degger [83]

It is answer choice A because you have to take the the GCF of each number which is 2x. Then if you were to divide the numbers by 2x you would put those numbers in the brackets.
$2x( x^{2} +2x+4)$ because $2x^3/2 x = x^{2}$ and $4 x^{2} /2x = 2x$ and $8x/2x = 4$
