Answer:
X=1 because 2+5=7 then X=1 cause 1*2=2
Step-by-step explanation:
Answer:
no, its not
Step-by-step explanation:
it does not have an angle of 90°
It is a scalene triangle
Answer:
see the procedure
Step-by-step explanation:
we have

we know that
The domain of a function is the set of all possible values of x
The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.
In this problem
The domain for x is the interval [0,∞)
All real numbers greater than or equal to zero
The range for y is the interval (-∞,0]
All real numbers less than or equal to zero
The graph in the attached figure
therefore
On a coordinate plane, an absolute value curve opens down and to the right in quadrant 4 and starts at (0, 0)
Answer:
it should be about 60 degrees
Given:
Right triangle XYZ has right angle Z.

To find:
The value of
.
Solution:
We know that,



For a triangle, all trigonometric ratios are positive. So,

It is given that
. After substituting this value in the above equation, we get




On further simplification, we get


Therefore, the required value is
.
