Answer:
Option 4 : 19
Step-by-step explanation:
For trapezoid ABCD : AB = 16 and CD = 28
E and F are midpoints of the legs
So, EF = (AB + CD)/2 = (16+28)/2 = 44/2 = 22
GH be the median of ABFE
So, GH = (AB + EF)/2 = (16+22)/2 = 38/2 = 19
Answer:
Length = 21 cm
Width = 14 cm
Step-by-step explanation:
Let the width of the jewel case = m cm
So, the length of the case = (m + 7) cm
Area of the case = 
Now, Area of a Rectangle = Length x Width
= m x (m + 7)
⇒ m x (m + 7) = 294
or, 
⇒ 
or, 
⇒(m + 21)(m -14) = 0
Hence, either (m + 21) = 0 ⇒ m = -21
or, (m -14) = 0⇒ m = 14
Since, m is the width of a case, so it can not be negative
Hence the width of the jewel case = m = 14 cm
And the length of the case = (m + 7) = 14 + 7 = 21 cm
Answer:
(2, 3)
Step-by-step explanation:
Since the problem says to add 5 to x, and subtract from y, you can do x = -3 + 5 and y = 4 - 1 to get (2, 3)
Answer:
50 degree
Step-by-step explanation:
the angle sum property of the equilateral triangle is =180 degree
since, 52 degree +78 degree +x =180 degree
130 degree + x =180 degree
x= (180-130) degree
<h3> x= 50 degree</h3>
