Answer:
Vertical angles are congruent, so L3 = 37 degrees, and L4 = 143 degrees.
Let me know if this helps!
Let x = the unknown angle
sine of an angle is measure of the opposite leg divided by the hypotenuse.
sin x = 10/21
To now solve for x, we so the inverse of sine.
sin⁻¹(10/21) = x
Plug this into your calculator.
x ≈ 28.44 degrees. This would round down to 28 degrees, option B is your answer.
Slope intercept form is y = mx + b
m=slope and b=y-intercept
In this equation m is 2 and b is -3
That means that you will plot a point at -3 on the y axis and go up 2 and right 1.
You will continue to do that and you will get some points
Some points you will get are (-2,-7) (-1,-5) (1,-1) (2,1) (3,3) (4,5) (6,9)
Hope this helped!
Step-by-step explanation:
5x - 5° = 40° ( being vertically opposite angles)
5x = 40° + 5°
5x = 45°
x = 45°/ 5
x = 9°
Now
< 1 = 5 * 9° - 5 = 45° - 5° = 40°
Hope it will help :)
