What is the value of n?

bogdanovich [222]

Answer:

Step-by-step explanation:

Look at the picture.

We know: Angles on one side of a straight line always add to 180°.

Therefore:

$\alpha=180^o-142^o=38^o\\\\\beta=180^o-133^o=47^o$

We know: the sum of the measures of the angles of the triangle is equal to 180 °.

Therefore:

$\gamma+47^o+38^o=180^o$

$\gamma+85^o=180^o$ <em>subtract 85° from both sides</em>

$\gamma=95^o$

$n^o+95^o=180^o\to n^o=180^o-95^o=85^o$

For a trapezoid, the following formula relates the area a, the two bases a and b, and the height h. a= g (a

Dovator [93]

A - area of a trapezoid;
a, b - two bases.
A = h * ( a + b ) / 2 / * 2 ( we have to multiply both sides by 2 )
2 A = h *( a + b )
2 A = h a + h b
h b = 2 A - h a
b = ( 2 A - h a ) / h
b = 2 A/h - a
