The ratios are both identical
sin x = perpendicular/hypotenuse = 3/5
cosy = base/hypotenuse = 3/5
Answer:
70
Step-by-step explanation:
all the angles of a triangle sum 180, so 180 - (70 + 40) = 70
0.4,1.04,1\2,2\3 that is the way to to shortest to the longest
The equation would be 5+4x=7x+11
Which comes out to:
x = - 2
It would be B) 3/15
You distribute 5 to both 3x and 4, giving you 15x+20=23
Then, you subtract 20 from both sides of the equation, giving you 15x = 3
And then you divide both sides by 15 so you can isolate x
