Answer:180.3
Step-by-step explanation:
a=150
b=50
C=120
c^2=a^2+b^2-2 x a x b x cosC
c^2=150^2+50^2-2x150x50xcos120
c^2=150x150+50x50-2x150x50xcos120
c^2=22500+2500-15000cos120
c^2=25000-15000x-0.5
c^2=25000+7500
c^2=32500
c=√(32500)
c=180.3
Answer:
Step-by-step explanation:
+ 3 = -z
= -z - 3
Square both sides , we have
2z = 
2z =
+ 6z + 9
re arranging the equation , we have
+ 6z - 2z + 9 = 0
+ 4z + 9 = 0
This will give a complex roots , solving by quadratic formula
z = -2 +
i , -2 -
i
Answer:
y=-1/2x+2
Step-by-step explanation:
for x-intercept
put y=0
0= -1/2x+2
1/2x=2
x=4
(4,0)
for y-intercept
put x=0
y= 2
(0,2)
In Triangle
ABC with the right angle at C, let a,b, and c be the opposite, the adjacent, and the hypotenuse of ∠A. Then, we have
sin A=ac⇒m∠A=sin−1(ac)
sin B=bc⇒m∠B=sin−1(bc)
I know its not the answer but I hope it was helpful
Answer:
x = (h-12y-2)/4
Step-by-step explanation:
Here, we want to make x the subject of the formula
We have this as:
h = 4x + 12y + 2
4x = h-12y-2
x = (h-12y-2)/4
