Together they equal 90 degrees.
Equation:
(0.1x - 22) + (0.3x - 54) = 90
Open parenthesis and simplify:
0.4x -76 = 90
0.4x = 166
DIvide:
Your final answer is x= 415
Hope this helps!
Answer:
10-6=4
if your friend took 6 apples out of the 10 you have you would have 4 left.
Step-by-step explanation:
I guess you mean 4/5 and 3/5
this is a right angled triangle with side 3-4-5 so 5 is the hypotenuse
sin x = opp / hyp = 4/5 so the opposite side is 4
cos x = adj/hyp = 3/5 so the adjacent side = 3
so tan x = opp/adj = 4/3

Answer:
125˚
Step-by-step explanation:
The angles given are supplementary. So we can set up the equation :
(3x+5)+(x+15)=180
Then we can solve for x.
Combine like terms:
4x+20=180
4x+20-20=180-20
4x=160
4x/4=160/4
x=40
Now we plug in 40 for x.
3(40)+5=<A
120+5=<A
<A=125
