1 answer:
The value of x in the triangle is (d) 7
<h3>How to solve for x?</h3>The complete question is in the attached image.
From the attached image of the triangle, we can see that the triangle is a right triangle, and x can be solved using the following sine function
Evaluate sin(45)
Solve for x
Divide
x = 7
Hence, the value of x in the triangle is (d) 7

Answer:
Step-by-step explanation:
The given line is defined by: , where we see that the slope is 5 and the y-intercept 1.
In order to find a line perpendicular to the given one, we need it to have a slope that is the "opposite of the reciprocal" of the given slope.
"Opposite" means it would have its sign inverted (in our case from positive to negative); and "reciprocal means that instead of 5, it would be its reciprocal: .
We can write this new line with such slope, and try to find its y-intercept (b) by using the given condition that requires it to go through the point (-5,-4) on he plane:
we require then that when , the value of
.
Therefore:
Then our final answer is that the new line should have the form:
