Step-by-step explanation:
A straight line has an angle of 180
132+(2x+3)=180
2x+3=48
2x=45
x=45/2
PLEASE GIVE BRAINLY
Answer:
y = 6/(x - 8).
Step-by-step explanation:
z = k/y where k is a constant
2 = k/3
k = 6.
So z = 6/y
and x = 6/y + 8
Multiply through by y:
xy = 6 + 8y
xy - 8y = 6
y(x - 8) = 6
y = 6/(x - 8)
Answer:
18 cm^2
Step-by-step explanation:
The legs of a right triangle are the base and height of the triangle.
Since C is a right angle, AB is the hypotenuse.
AC and BC are the legs and the base and height.
sin 75 = BC/12
BC = 12 sin 75
cos 75 = AC/12
AC = 12 cos 75
area = bh/2 = (12 sin 75)(12 cos 75)/2
area = 18 cm^2
7 7/8 can be estimated to 8
2 2/11 can be estimated to 2
8 + 2 = 10
7 7/8 = 56+7/8 = 63/8
2 2/11 = 22+2/11 = 24/11
63/8 + 24/11 = 693+192/88 = 10.06
So do you see how similar 10 and 10.06 are to each other? :)
