How to solve for x if Sin(x-20)= Cos(3x+10) |
|
Answer» Step-by-step EXPLANATION: sin(x−20 ∘ )=cos(3x−10 ∘ ) ⇒sin(x−20 ∘ )=sin(90 ∘ −(3x−10 ∘ )) SINCE sin(90 ∘ −θ)=cosθ ⇒x−20 ∘ =90 ∘ −(3x−10 ∘ ) ⇒x−20 ∘ =90 ∘ −3x+10 ∘
⇒x+3x=100 ∘ +20 ∘ =120 ∘
⇒4x=120 ∘
∴x= 4 120 ∘
=30 ∘ |

(i) In AABC, DE | AB,DC =2BDA(ACDE)=20 cm thenfind A(OABDE) |
|
Answer» Answer: The basic proportionality theorem STATES that if a LINE is drawn parallel to one side of a triangle and it intersects the other two sides at two distinct points then it DIVIDES the two sides in the same ratio. It is given that AD=8 CM, AB=12 cm and AE=12 cm. Using the basic proportionality theorem, we have AB AD
= AC AE
= BC DE
⇒ AB AD
= AC AE
⇒ 12 8
= AC 12
⇒8AC=12×12 ⇒8AC=144 ⇒AC= 8 144
=18 Now, CE=AC−AE=18−12=6 cm Hence, CE=6 cm. |

0.345 with bar in 345 write in p/q form answer with explanation I will give you the brainliest |
|
Answer» Step-by-step EXPLANATION: First CONSIDER x=0.345 345,because there is a bar above the 3 digits. The NUMBERS after the POINT repeats.Take this as 1. Next multiply by 1000 on both the sides. Because ,as there is a bar on THREE digits we should write as 1000.Take this as 2. Next we have to subtract 1 from 2. that is 1000x =345.345 - x = 0.345 ----------------------- 999x = 345.000 ------------------------ then we get 999x=345.000 999x = 345 x= 345/999 |
