Lines AB and AC are equal so you set up an equation like so...
4x + 1 = 2x + 23
Subtract 1 from both sides.
4x = 2x + 22
Subtract 2x from both sides.
2x = 22
Divide.
x = 11
Now you need to plug in 11 into 3x - 8.
3(11) - 8
= 33 - 8
= 25
So BC is 25.
I hope this helps love! :)
The slope of the line is negative
Okay
now draw a right angled triangle
labeling the hypotenus 57ft
the opposite x and the adjacent 5.5 ft and the angle in the right angle triangle is 55 °.
now solve
sin 55°=x/5.5
0.8192(the sin of 55)= x/5.5
cross multiply
X=4.51
The supplement angle of angle ABC is 108 degrees because, supplement angles mean angles that add up each other to 180 degrees so 180-72=108
