Answer:
38
Step-by-step explanation:
By CPCTC, angles C and D are congruent.
130 = 4x - 14
144 = 4x
x = 38
It's 18 it means 18 times 3 becomes 54 and that's how you get it
Answer:
Step-by-step explanation:
The formula for determining the surface area of a sphere is expressed as
Surface area = 4πr^2
Where
r represents the radius of the sphere
π is a constant whose value is 3.14
From the information given,
Surface area of the sphere = 100 centimeters ^2. Therefore,
100 = 4 × 3.14 × r^2
100 = 12.65r^2
r^2 = 100/12.65 = 7.9051
r = √7.9051
r = 2.81 centimeters
Answer:
- The value of

- The value of

Step-by-step explanation:
Let

and

As
is exactly divisible, so, the remainder is 0.
∴ 

As the R.H.S becomes 0 when
and
.
And
by substituting 

![25 + 20( \frac{\sqrt{5}}{\sqrt{2}} ) + a( \frac{\sqrt{5}}{\sqrt{2}}) +b =0...[A]](https://tex.z-dn.net/?f=25%20%2B%2020%28%20%5Cfrac%7B%5Csqrt%7B5%7D%7D%7B%5Csqrt%7B2%7D%7D%20%29%20%2B%20a%28%20%5Cfrac%7B%5Csqrt%7B5%7D%7D%7B%5Csqrt%7B2%7D%7D%29%20%2Bb%20%3D0...%5BA%5D)
by substituting 
![25 - 20( \frac{\sqrt{5}}{\sqrt{2}} ) - a( \frac{\sqrt{5}}{\sqrt{2}}) +b =0.....[B]](https://tex.z-dn.net/?f=25%20-%2020%28%20%5Cfrac%7B%5Csqrt%7B5%7D%7D%7B%5Csqrt%7B2%7D%7D%20%29%20-%20a%28%20%5Cfrac%7B%5Csqrt%7B5%7D%7D%7B%5Csqrt%7B2%7D%7D%29%20%2Bb%20%3D0.....%5BB%5D)
Adding Equation [A] and equation [B]
