Answer:
j would be 130 cuz sides that are congruent have congruent angles so you add those two angles up and subtract from 180
Answer:
undefined
Step-by-step explanation:
Answer:
x=5
Step-by-step explanation:
distribute first
2(-4x+3)
-8x+6
-8x+6+3x+3=-16
combine like terms
then get the variable alone
-5x+9=-16
-9. -9
<u>-5x</u><u>=</u><u>-25</u>
-5. -5
x=5
Right angle i think
90 degree angle is right angle so jus Measure it
Answer: ( -0.731, 0.682)
Step-by-step explanation:
The unit vector is defined as a vector that points in the same direction as our vector (137 degrees from the x-axis) and has a magnitude of 1.
Knowing the angle, is really simple to do it.
First, we know that for a radius R and an angle A, the rectangular coordinates can be written as:
x = R*cos(A)
y = R*sin(A)
And if we want that the magnitude/modulus of our vector to be 1, then R = 1, and we know that A = 137°
x = 1*cos(137°) = -0.731
y = 1*sin(137°) = 0.682
Then the unit vector is: ( -0.731, 0.682)
