In a 30-60-90 triangle, the opposite sides occur in a 1-sqrt(3)-2 ratio. This means the side opposite the right angle occurs in a ratio of
with the longer leg. So the hypotenuse has length
Given:
Figure of similar triangles.
To find:
The value of x and the measure of NR.
Solution:
In triangle RST and RMN,
(Vertically opposite angles)
(Alternate interior angles)
(By AA property of similarity)
We know that, corresponding sides of similar triangles are proportional.
On further simplification, we get
The value of x is 7.
Now,
Therefore, the value of x is 7 and the measure of NR is 12 units.
Answer:
45 - 25 = 20 / 10 = 2 meaning he used the boat for 2 hours.
Step-by-step explanation:
Its the same this as before you start by writing it out how the way PEMDAS works. PEMDAS is ( Parenthesis, Exponents, Multiplication, Division, Adding, and Subtraction). Also i accidentally messed up my other answer so give me a sec.
Answer:
x = -2
Step-by-step explanation:
Add 3 to both sides of the equation.
x = -5 + 3
Add -5 and 3
x = -2

Ok so it’s pretty much be D. kinda hard to explain but i hope it helped
