Answer:
21√10
Step-by-step explanation:
√3 x 7√30
= 7 √30 x 2
= 7√90
____________________________________________________________
Simplifying 7√90
7√90
= 7 √9 x √10
= 7 x 3 x √10
= 21 x √10
= 21√10
Answer:
(a) x=45°
(b) If AD was parallel to BC, <A would be equal to (180-<B)=90 (corresponding angles). Since <A≠90, we can see that AD and BC aren't parallel.
Step-by-step explanation:
(a)
Angles in a quadrilateral add to 360:
<A+<B+<C+<D=360
2x+90+x+3x=360
6x=270
x=45°
(b)
If AD was parallel to BC, <A would be equal to (180-<B)=90 (corresponding angles). Since <A≠90, we can see that AD and BC aren't parallel.
1/4(2x-14)=4
0.5x-3.5=4
0.5x = 4 + 3.5
0.5x = 7.5
x = 15
Answer:
a)......1+2=90 degree.....
so,x+x-20=90=2x=110
x=55degree
Step-by-step explanation:
b)let it be a triangle....angle1=56
2=y
3=29....by vertically opposite angles
by ext angle property... x= 1+3=56+29= 85
