A garden in the shape of a trapezoid has an area of 44.4 square
Leviafan [203]

Answer:

37 meters

Step-by-step explanation:

The equation for the area of a trapezoid is A=\frac{a+b}{2} +h.

Here, a = 4.3, b=10.5, and h is unknown.

44.4=\frac{4.3+10.5}{2} +h

44.4=\frac{14.8}{2} +h

44.4=7.4 +h

37 = h

The height of the trapezoid is the width of the garden, so the garden is 37 meters wide.

FIND X AND Y. GIVING BRAINLIEST AND 100 POINTS
aksik [14]

Answer:

here u can look

Mark as brainlist

Step-by-step explanation:

X + y = 120(being alternate angle)

or,X=120-y

then

2x-y=120

or,2(120-y) - y= 120

240-2y-y=120

y=240-120

y= 120

again,

X=120-y

= 120-120

=0

hence,

X= 0

y= 120
