Answer:
B
Step-by-step explanation:
- From the property of parallelogram the opposite angels are equal so < DAB = < DCB so < DAB will become 16x.
9x + 5 + 16x(<DAB) = 180 ....... because it is straight line.
25x + 5 = 180
25x = 180 - 5
25x = 175
x = 7
- now let's substitute in the angle < DCB( 16x):-16 × 7= 112
- To get < ABC lets use the property of parallelogram which says tha adjacent angles are supplementary. which means <ABC + <DCB = 180
<ABC + 112 = 180
< ABC = 180 - 112
< ABC = 68
IT WAS SO DIFFICULT TO EXPLAIN WITH PHONE BUT I TRIED MY BEST
hope it helps
for any question comment me ❤❤
Answer:
Natural numbers are the counting numbers, meaning that they make up the set {1,2,3,4,5,...} So , 4/5 is belong to natural number
Car normally has 4 wheeles
motorcycles normall have 2 wheels
c=cars
m=motorcycles
4c+2m=98
c+m=30
multiply second equation by -2 and add to the original equaiton
-2c-2m=-60
4c+2m=98 +
2c+0m=38
2c=38
divide 2
c=19
sub
c+m=30
19+m=30
m=11
11 motorcycles
19 cars
Answer:
9
Step-by-step explanation:
similar triangles.
that means there is one common factor to transform the lengths of all lines from one triangle to the other.
it looks to me DF is the longest side in DEF, and that would make it associated to BC of ABC.
so, the factor is then
BC = DF×f
24 = 12×f
=> f = 2
so, EF then is associated to AC.
AC = EF × f
18 = EF × 2
EF = 18/2 = 9
Answer:
Step-by-step explanation:
b/c these are similar triangle we can say this ratio of the two triangles is true
15/x = 31/(44+x)
now just use algebra to solve for x
15*(44+x) = 31x
660+15x = 31x
660=16x
41.25 =x
41.3 looks good
