The opposite angles of a parallelogram have measures of (3x-20) and (x+15). Find x

KiRa [710]

ANSWER

The value of x is,

$17.5$

EXPLANATION

We were given that the opposite angles of a parallelogram are

$3x - 20$ and $x + 15$ .

The opposite angles of a parallelogram are equal.

We can write the equation below in x and use to find the value of x.

$3x - 20 = x + 15$

We group like terms to obtain,

$3x - x = 15 + 20$

This implies that,

$2x = 35$

We divide both sides of the equation by 2 to obtain,

$x = 17.5$

Gnom [1K]

Answer:

1024/59049

Step-by-step explanation:

P( clear hurdle) = 2/3

There are 10 hurdles

P ( clear all hurdles) = P( clear hurdle) * P( clear hurdle)...... 10 times

= 2/3 * 2/3 *....... 10 times

= (2/3) ^ 10
