Answer:
option B. 
Step-by-step explanation:
we know that
1) The two diagonals of a rhombus are perpendicular
2) The sum of the interior angles in any triangle must be equal to 180 degrees
Let
O ----> the intersection point of the diagonals of the rhombus
In the right triangle OAD
solve for x
true: y = 9 would give us a straight line because of two reasons:
a: we don’t know if x is rising
b: we don’t have an x in the equation
<span>Solve for "x":
a/x = x/4a
---
x^2 = 4a^2
x = 2a</span>
Answer:
C.
Step-by-step explanation:
A one to one function is a function in which an element in a domain is corresponding to the a single element in the range. That is, each element in the domain has exactly one image in the range.
To answer the question that say : What is a one-to-one function?
A function f is called a one-to-one function if it never takes on the same value twice.
Therefore the correct answer is option C.
<span>We have to find the value of x if the measures of the angles of a triangle are: 2 x, 3 x and 4 x. We know that the sum of the measures of the angles of a triangle is 180 degrees. A + B + C = 180. Here we have: A = 2 x, B = 3 x and C = 4 x; 2 x + 3 x + 4 x = 180; 9 x = 180; x = 180 : 9. Answer: x = 20 degrees.</span>
