Mathematics

Degger [83]2 years ago
6 0

Step-by-step explanation:

the given shape is a parallelogram so, adjacent angles are supplementary.

so,

=》3y - 15° + 2y = 180°

=》5y = 180° + 15°

=》y = 195° ÷ 5

=》y = 39°

now , Angle A = Angle C

( they are opposite angles of a parallelogram )

=》Angle A

=》 2 × y

=》2 × 39°

=》78°

hence, Angle A = 78°

alexgriva [62]

Answer:

A = 54.8 - (1200/x) - 2x

Step-by-step explanation:

Given <em>x</em> the wide and <em>y</em> the height, we have

x*y = 50

⇒  y = 50/x

The area of the printed region is A = w*h

where

Wide: w = (x-2*1.2) = x-2.4

Height: h= (y-2*1) = y-2

then

A = (x-2.4)(y-2) = xy - 2.4y - 2x + 4.8 = 50 - 24*(50/x) - 2x + 4.8

⇒  A = 54.8 - (1200/x) - 2x

C is the correct answer. A line is proportional if it is a straight line that passes through the origin, and while it does pass through the origin, it isn’t completely straight.
