Answer:
Step-by-step explanation:
3 : 12
Both have table of 3 in common so
1 : 4 or 1/4
4 : 64
Both have table of 4 in common
1 : 16 or 1/16
Bisect typically means half but since we aren't given angle at the start so we can just have to solve for x.
(3x + 8) = (5x - 4)
3x = 5x - 12
-2x = -12
x = 6
Best of Luck!
Answer:
LN= 68°
Step-by-step explanation:
Answer: perimeter = 96mm, Area = 564mm².
Step-by-step explanation:
From the diagram, it is a trapezium, it has a rectangle joined together by a right angled triangle. Now to find the perimeter, we add all the dimensions together. To get the other side of the rectangle, which is also the perpendicular height of the figure, we take the Pythagoras. Let the perpendicular height = x
Therefore,
25² = ײ + 7²
625 = x² + 49
x² = 625 - 49
x² = 576
x. = √576
= 24.
Now the perimeter
= 20 + 25 + 7 + 20 + 24
= 96mm.
Area of the figure will be
= 1/2( a + b )h
Where a = 20, b = 20 + 7 = 27 and h = 24, now substitute for the values
( 20 + 27) x 24
---------------------
2
= 47 x 24/2
= 47 x 12
= 564mm²
