Answer:
FE = 30°
Step-by-step explanation:
arc FGC = arc FG + arc GB + arc BC
220° = 90° + arc GB + 70° . . substitute known values
60° = arc GB . . . . . . . . . . . . . subtract 160°
__
External angle A is half the difference of arcs EG and GB:
30° = (1/2)(arc FE +90° -60°) . . . substitute known values
60° = arc FE + 30° . . . . . . . . . . . multiply by 2 and simplify
30° = arc FE . . . . . . subtract 30°
_____
The key to this problem is the relationship between external angle A and the measures of the arcs it subtends.
Answer:
option A is correct.(Every plane must have three intercepts.)
Step-by-step explanation:
" Three-dimensional space (also: 3-space or, rarely, tri-dimensional space) is a geometric setting in which three values (called parameters) are required to determine the position of an element (i.e., point). This is the informal meaning of the term dimension "
The intercept form of the equation of plane in 3-D is given by:
Where l,m,n are intercepts of x,y,z axes and a plane respectively.
Hence, we require all the three intercepts of a every plane.
Hence, option A is correct.
I think the answer is find it out your dang self LOL #DEEZNUTZ
Answer:
x+y=44 and y=x+2
Step-by-step explanation:
Answer:
The answer is (a) ⇒ tanx = sinx/cosx
Step-by-step explanation:
∵ (sinx)(cosx)(tanx) = (sinx)(cosx)(sinx/cosx) = sin²x
∵ sin²x = 1-cos²x
∴ L.H.S = R.H.S
∴ (sinx)(cosx)(tanx) = 1 - cos²x
