1 - ( 1 / x) i dont know what you're trying to get but thats what i think.
Answer:
.681818
Step-by-step explanation:
In order to find what 8 is with a 25% increase
First lets find out what 25% of 8 is
So in order to find it we multiply 25% by 8
to make things easier we change the 25% to a decimal
25% = 0.25
Now we can multiply.
0.25 x 8 = 2
So since this is a increase we take 8 and add our 25%
25% of 8 = 2
we want an extra 25% with 8
so we add!
8 + 2 = 10
Answer = with a 25% increase 8 becomes 10
Answer:
(b).
i). g=75° ii) x=70° iii) n=60°
(c). n=69°
Step-by-step explanation:
Given,
i) Two sides are equal that means the triangle is an isosceles triangle.
We know opposite angles of isosceles triangle are equal.
That means
ii)The third vertex of the larger triangle will have an angle of
Thus there will be 20° next to 30°.
Therefore
iii) All sides are equal thus it is an equilateral triangle.
Therefore each angle is degree.
c) Linear pair of 111° would be 180-111=69°
We see that is corresponing to
Therefore
