a) Area of rhombus = ½ * (diagonal1)*(diagonal 2)
Let diagonal (D2 )= longer diagonal = 15 and diagonal (D1) = shorter diagonal
90 = ½ (D1)*15
90 = 7.5 D1
Now divide both side by 7.5
90/7.5 = d1
D1= 12 units.
b) Area of rhombus = ½ * (diagonal1)*(diagonal 2)
Let the ratio be 
Diagonal 1= 
Diagonal 2= 
147 = ½ * 
Multiply both side by 2
294 =
294 = 6
Divide both side by 6
294/6 = 6/6
49 =
= 7 unit
Answer:
50°
Step-by-step explanation:
Let :
Let the angle = x
Second angle = x + 10
Third angle = x - 10
Sum of angles in a triangle = 180
x + (x + 10) + (x - 10) = 180
x + x + 10 + x - 10 = 180
3x = 180
x = 180 / 3
x = 60
Smallest angle :
x - 10 = 60 - 10 = 50°
Answer:
<u>18 and 19</u>
Step-by-step explanation:
Let the integers be x and x + 1.
=> 2(x + 1) = 3x - 16
=> 2x + 2 = 3x - 16
=> x = 18
=> x + 1 = 19
The integers are :-
<u>18 and 19</u>
Answer:
42 km per hr
Step-by-step explanation:
5.6cm x 3000000cm = 16800000 cm
16800000cm / 100000km = 168 km
168km / 4hrs = 42 km per hours
