Answer:
x=13.5
Step-by-step explanation:
4.5/6=x/18
cross multiply
6x=18(4.5)
6x=81
x=81/6
x=13.5
Answer:
-4 and -5
Step-by-step explanation:
Love u man :)
Step-by-step explanation:
The ratio cosine tell us that
- In a right angled triangle, the cosine of an angle is the side adjacent to the angle divided by the hypotenuse of the triangle.
In other words,
The side adjacent to angle a is 9. The hypotenuse is 41.
So
Answer:
x=3 and y=5 passes through(3,5)
x=2 and x=3 is perpendicular to y=3
so anwer is x=3
Answer:
25 degrees
Step-by-step explanation:
The sum of the 80 and 55 degree angles and the unknown angle x must be 180 degrees. Thus, x + 80 + 55 = 180, or x + 155 = 180, or x = 25.
x is 25 degrees.
This is based upon the "corresponding angles" principle. Lines AB and CD are parallel and are intersected by the longer diagonal line if we extend this line past the 80 and 55 degree angles.
