Actually Welcome to the Concept of the Similarities.
Since here, first figure is a Triangle, hence similarity of a triangle is given by ratio of it sides and make them equate,
hence for,
1.) 16/12 = x/9 ===> 4/3 = x/9 ===> x = 9*4/3 ==> x = 36/3
hence the value of x is 12 , ===> x = 12 .
2.) here,in the case of a Reactangle the relation is such that, length = 2* breadth,
hence we apply the relation,
x = 2*4.5 ===> x = 9 units.
So you have a right angle triangle. You need to use trig for this, as you have two values you can figure out a third.
You know that you have
90 deg. angle
19 deg. angle
Therefor you have 71 deg. angle
sin19 = x/15
15sin19 = x
x = 2.2
Now do Pythagoras c^2-b^2=a^2
a = 14.8
So the sides are 2.2 and 14.8 units long. (If these numbers are wrong tell me and I'll edit answer)
Step-by-step explanation:
cot²x − cot x − 42
(cot x − 7) (cot x + 6)
No I guess sorry if you get it wrong
Answer:
The correct answer is D
xlog(r) - xlog(s) - xlog(t)
= log(r^x) - xlog(s^x) - xlog(t^x)
= log(r^x / s^x / t^x)
= log(r^x / (s^x * t^x))
= log((r / (s * t))^x)
