This is an isosceles triangle. Therefore, at the base we have congruent angles (look at the picture).

We have the equation:

(5x + 13)° + (3x + 7)° = 180°

5x + 13 + 3x + 7 = 180 combine like terms

(5x + 3x) + (13 + 7) = 180

8x + 20 = 180 subtract 20 from both sides

8x = 160 divide both sides by 8

1. 1 and -1 are two such rational numbers whose multiplicative inverse is same as they are.

2. absolute value is resembled using the formula : |x|

Here,

$\hookrightarrow \sf |\dfrac{-3}{11} |$

$\hookrightarrow \sf \dfrac{3}{11}$

final answer: 3/11

$\hookrightarrow \sf \dfrac{1}{2} \div \dfrac{3}{5}$

$\hookrightarrow \sf \dfrac{1}{2} * \dfrac{5}{3}$

$\hookrightarrow \sf \dfrac{5}{6}$

Associative property can only be used with addition and multiplication

How do we find the breadth of square if perimeter and length is given

madreJ [45]

Answer:

A square has 4 sides of equal length, so if you have been given the length, this is also the breadth.

Therefore, the perimeter is 4 x side length.

For example, imagine a square with side length 3 cm. As all four side lengths are equal, the perimeter would be 4 x 3 cm = 12 cm
