Answer:
X=1÷2,Y=32°
Step-by-step explanation:
in right angled traingleRST
<R+<T<S=180(INTERIOR ANGLE OF TRAINGLE)
Y-2+90+60=180(S=60°BEING ONE ANGLE OF EQUILATERAL TRAINGLE)
Y+148=180
Y=180-148=32
NOW,
UT=5X(RT BISECTS TS AND UT EQUALLY)
RU=US(SIDE OF EQUILITERAL TRAINGLE IS EQUAL)
8X+1=UT+TS
8X+1=5X+5X
1=10X-8X
1=2X
X=1/2
Solution:
we have been asked to sketch a plane containing points E, D and B.
where E and B are collinear with A. It mean all thses three points will fall on a straight line. Also D is a vertex where CD and FD meets.
The sketch has been attched below.
Here as you can see three points are in a staright line and we have another one in whuch two vectors CD and FD are meeting at the vertex D.
Answer:
JKL=BCA
Step-by-step explanation:
Answer:
-9-5x
Step-by-step explanation:
they aren't the same because of the variable on 5x. You can simplify the problem to -9-5x but that's about it unless it equals something.
Answer:
A
Step-by-step explanation:
Remark
f and d are equal (and acute) because they are corresponding angles.
82 and f are supplementary, so we can find f
Finding f
f + 82 = 180
f = 180 - 82
f = 82
Finding d
d = f
d = 82
