Answer:
Step-by-step explanation:
if we have a right triangle,
one angle=90
180-90=90
let x be one angle, and y another angle
the other is 2x+30
x+2x+30=90
3x=60
x=20
y=70
Answer:
c
Step-by-step explanation: If you do the math you can clearly see and I got the answer correct.
Answer:
10y-30
Step-by-step explanation:
10*1y=10y
-3*10=-30
10y-30
If arctan 4/3 = the tangent of that angle will be 4/3 , opposite 4 over adjacent 3
Now, you only have to take the sin of that angle it's opposite 4 over hypotenuse 5.
You will get that the answer is 4/5
hope this helps
You only can if 341 has a decimal of some sorts. other than that, you cannot round it.
