Answer:
a) see attachment
b) base: 4, height: 4√3
c) area: 16√3
Step-by-step explanation:
a) The figure is drawn in the attachment
__
b) The side lengths of a 30-60-90 right triangle have the ratio ...
1 : √3 : 2
Multiplying these by 4 gives the side lengths of each triangle created by the diagonal. The base (short leg) is 4 units; the height (long leg) is 4√3 units.
__
c) The area is the product of base and height:
A = bh
A = 4(4√3) = 16√3 . . . . square units
Answer:
x = 5.2
Step-by-step explanation:
See the diagram first.
We know that in a triangle if we draw a line parallel to the baseline then it will divide the other two lines of the triangle in the same ratio.
Therefore, from the given figure it is clear that 
⇒ 3x = 26 - 2x
⇒ 5x = 26
⇒ x = 5.2 (Answer)
Answer:
m = -4.33333 or -4 and 1/3
Step-by-step explanation:
gradient = (difference in y)/(difference in X)
m = (-1-12)/(8-5)
m = -13/3
m = -4.3333333
Answer:
One Way: 6/9 = 2/3
Step-by-step explanation:
You have to divide. Divide the numerators 6 by 3 and divide 9 by 3 on the denominator.
9/20
45% is 0.45. To switch into a fraction you do 45 over 100, simplified is 9/20.
