Step-by-step explanation:
You got the right equation
Answer:no
Step-by-step explanation: because it is an acute triangle
1 is incorrect. to solve for f, you have to get it alone, and right now you have a negative sign in your way.
you can eliminate the negative by dividing both sides by -1:
-f = -100
divide by -1 to cancel out the - in front of f
f = 100
That whole thing is a right angle, which is 90 degrees. put measure 1 and 2 and equal it to 90 and solve. 5x+x-12=90. combine like terms and solve for x. 6x-12=90. 6x=90+12. 6x= 102. x=17
False cube root of 1 is plus 1 only.
