Answer:
(d) see attached
Step-by-step explanation:
All of the answer choices show shading above a dashed line, so we need to look a little closer at the equation of the boundary line. Written as an equation, it is ...
3x +y = 9
When you set each variable to zero and solve for the other, you find the intercepts to be ...
y = 0, x-intercept: 3x = 9 ⇒ x = 3
x = 0, y-intercept: y = 9
The only graph that has x- and y-intercepts matching these values is the one attached.
Given:
The figure of a rhombus.
To find:
The value of x.
Solution:
We know that, if two lines intersect each other, then the vertically opposite angles are equal.
From the given figure it is clear that the diagonals intersect each other and construct two pairs of vertically opposite angles.
Since and
are vertically opposite angles, therefore
Hence, the value of x is 95°.
