Answer:
x = 32°
Step-by-step explanation:
Given:
Line AB║CD
Angle 1 = (2x + 15)°
Angle 4 = 101°
Find:
Value of x = ?
Computation:
We know that Angle 1 and Angle 4 stay on same line , so Angle 1 and Angle 4 are liner pair.
∴ Angle 1 and Angle 4 = 180°
⇒ (2x + 15)° + 101° = 180°
⇒ 2x + 116° = 180°
⇒ 2x = 180° - 116°
⇒ 2x = 64°
⇒ x = 32°
Therefore value of x 32°
Answer:
0.4
Step-by-step explanation:
100(0.4)=40
The exchange rate from <span>£ to € would be 1/0.72 or 1 to 1.889</span>
Answer:
f = .39
Step-by-step explanation:
d (v) = 2.15 v^2 / (64.4 f)
v = 40
d = 138
substitute these in
138 = 2.15 (40)^2 / (64.4 *f)
simplify
138 = 2.15 (*1600) / (64.4 *f)
138 = 3440 / (64.4 *f)
multiply each side by 64.4f
138 * 64.4 f = 3440
8887.2 f = 3440
divide by 8887.2
8887.2 f /8887.2= 3440/8887.2
f=.38707
to the nearest hundredth
f = .39
Answer:
The perimeter of the Rhombus is 100 cm
Step-by-step explanation:
First of all, we will need to find the length of the other diagonal.
let’s call the diagonals p and q
Mathematically, the area of the Rhombus is;
pq/2 = Area of Rhombus.
Let’s call the missing diagonal p
So;
(p * 14)/2 = 336
14p = 672
p = 672/14
p = 48 cm
Now, we can find the perimeter of the Rhombus using these diagonals.
Mathematically;
P = 2 √(p^2 + q^2)
Substituting these values, we have;
P = 2 √(14)^2 + (48^2)
P = 2 √(2500)
P = 2 * 50
P = 100 cm
