Answer:
70° is the answer hope it helps
30°+90°+ 3y= 180°
120°+3y= 180°
3y= 180°-120°
y= 60°/3
y= 20°
Now
y°+90°+x°= 180°
20°+90°+x= 180°
x= 180°-110°
x= 70°
Answer:
15 : 29
Step-by-step explanation:
(3 3/4) / (7 1/4) = ((3·4+3)/4) / ((7·4+1)/4)
= (15/4) / (29/4) = 15/29
The ratio of the two numbers is 15 : 29.
9u-9t=18
original no. is 10t+u
reversed no. is 10u+t
so its (10u+t)-(10t+u)=18
which gives 9u-9t=18
Answer:
Yurrrrrrrrrrrrrrrrrrrrrrr
Step-by-step explanation:
Who got the answer to the homework
<h3>Answer: C) none of the equations are identities</h3>
If you plugged theta = 0 into the first equation, then you would have
sin(45) + cos(45) = sin(0) + cos(0)
sqrt(2) = 1
which is a false equation. We don't have an identity here.
The same story happens with the second equation. Plug in theta = 0 and it becomes
cos(60) - sin(60) = cos^2(0) + tan(0)
1/2 - sqrt(3)/2 = 1 + 0
-0.37 = 1
which is false.
