Answer:
Solution one is correct and solution 2 and 3 are incorrect
Step-by-step explanation:
You simply make an equation because for vertical angles 2 angles that are across from each other have the same value (in this case 2x+30 and 5x-36.)
The equation: 2x+30=5x-36---->3x=66----> x=22
Solution 1 is correct.
Hope this helped!
Solve for x by simplifying both sides of the equation, then isolating the variable.
x =−60
Step-by-step explanation:
mA=cosA=17/38
A=cos inverse of 17/38
A=63 degrees
