Answer:
x = 18.4
y = 35º
Step-by-step explanation:
cos∅ = adj/hyp
cos49 = x/28
28cos49 = x
x = 18.4
tany = opp/adj
tany = 19/27
y = arctan19/27
y = 35º
Answer:
Step-by-step explanation:
<span>2+3(x-3)+1-5(2-x)
The first thing we must do is distribute...
2 + 3x - 9 + 1 - 10 + 5x
Then we must combine like terms. We can combine terms with an x together and we can combine terms without an x together.
2 - 9 + 1 - 10 = -16
3x + 5x = 8x
So our simplified expression is C. 8x - 16</span>
Answer:
angles
1x
3x
5x
1x +3x +5x = 180 (ASP)
9x = 180
x= 180÷9
x= 20
1x= 20
3x= 60
5x=100
angles are 20°, 60°, 100°
