Answer:
6666666.667 equals x
Step-by-step explanation:
take the 3 to the other side- doin that is became positive
them you divide to find x
Answer:
C
Step-by-step explanation:
This triangle has a right angle so it is right.
It also has three different sides so it is scalene.
C is the answer
A) the missing degree is 166
b) the missing degree is 142
c)the missing degree is 160
I do hope I helped you in a way! If I am incorrect I apologize.
Let b=height of building. By similar triangles we can say:
b/44.75=3.1/1.29
b=44.75*3.1/1.29
b≈107.54
b≈108 meters (to the nearest whole meter)
Answer:
x = -7 ±3i
Step-by-step explanation:
(x+7)^2+9=0
Subtract 9 from each side
(x+7)^2+9-9=0-9
(x+7)^2=-9
Take the square root of each side
sqrt((x+7)^2) = ±sqrt(-9)
We know sqrt(ab) = sqrt(a) sqrt(b)
x+7 = ±sqrt(-1) sqrt(9)
We know that sqrt(-1) is the imaginary number i
x+7 = ±i *3
x+7 =±3i
Subtract 7 from each side
x+7-7 = -7 ±3i
x = -7 ±3i
