guapka [62]

Answer:

2.55

Step-by-step explanation:1

Convert 1121\frac{1}{2}1​2​​1​​ to improper fraction. Use this rule: abc=ac+bca \frac{b}{c}=\frac{ac+b}{c}a​c​​b​​=​c​​ac+b​​.

34+3.3−1×2+12\frac{3}{4}+3.3-\frac{1\times 2+1}{2}​4​​3​​+3.3−​2​​1×2+1​​

2

Simplify 1×21\times 21×2 to 222.

34+3.3−2+12\frac{3}{4}+3.3-\frac{2+1}{2}​4​​3​​+3.3−​2​​2+1​​

3

Simplify 2+12+12+1 to 333.

34+3.3−32\frac{3}{4}+3.3-\frac{3}{2}​4​​3​​+3.3−​2​​3​​

4

Simplify.

Can someone please answer this and explain how you got it? Or just show your work for it please and thank u <3
serg [7]

Answer:

please mark me as brainlist please

Step-by-step explanation:

we know, ∠BGA = 90

In right angled triangle BGA

AB = 12 cm (diameter of circle)

⇒ (AB)2 = (AG)2 + (BG)2

⇒ 122 = 82 + (BG)2

⇒ BG = 4√5

In right angled triangle BCG

Let CG be x cm.

⇒ (BC)2 = (CG)2 + (BG)2

⇒ (BC)2 = x2 + (4√5)2 ----(1)

As we know,

⇒ (BC)2 = CG × CA ----(2)

From equation (1) and equation (2)

⇒ x2 + (4√5)2 = x × (x + 8)

⇒ x2 + (4√5)2 = x2 + 8x

⇒ 8x = 80

⇒ x = 10 cm

From equation (2)

⇒ (BC)2 = CG × CA

⇒ (BC)2 = 10 × 18 = 180

⇒ BC = √180 = 6√5

6 × 5 = 30
