Here,

a-b=14

ab=8

<u>we</u><u> </u><u>know that</u><u>, </u>

\tt{(a-b)^2=a^2+b^2-2ab  } ⠀

<u>According</u><u> </u><u>to</u><u> </u><u>the question</u><u>, </u>

\tt{ (14)^2=a^2+b^2-2×8 } ⠀

\tt{196=a^2+b^2-16  } ⠀

\tt{a^2+b^2=196-16  } ⠀

\tt{a^2+b^2=180  } ⠀

Answer:

\bold{ a^2+b^2=212} 

Step-by-step explanation:

a-b=1

ab=8

So,

\mapsto{a^2+b^2-2ab=(a-b)^2   }     

\mapsto{a^2+b^2-2×8=(14)^2   } 

\mapsto{a^2+b^2-16=196  } 

\mapsto{a^2+b^2=196+16  } 

\mapsto{a^2+b^2=212   }

How do I solve the following by using substitution? <br> Y=4x+9<br> 10x=18 -2y
sergejj [24]
Plug 4x=9 in for y:
10x=18-2(4x+9)
10x=18-8x-18
10x=-8x
18x=0
x=0

now plug 0 in for x:
y=4(0)+9
y=9

to check, plug x and y back into one of the equations to make sure they are right:

10(0)=18-2(9)
0=18-2*9
0=18-18
0=0

What would be the answer? Or how do I solve it?
stellarik [79]

AB = √(8^2 + 6^2)

AB = √100

AB = 10

AC = √(8^2 + 15^2)

AC = √289

AC = 17

BC = 9

P= AB + AC + BC

P = 10 + 17 + 9

P = 36 units

34)

Area of ABC = 1/2 x 8 x 9

A = 36 square units

Sin A= ?<br>c/a<br>a/c<br>a/b<br>b/c​
S_A_V [24]

Answer:

\sin A = \frac{a}{b}

Step-by-step explanation:

Given:

We took here a Right Angle Triangle,Δ ABC at angle B as 90°

Side opposite to angle A = a

Side opposite to angle B = b = Hypotenuse

Side opposite to angle C = c

To Find:

Sin A = ?

Solution:

Property of a Sine rule for a Right Angle Triangle.

\sin A =\frac{\textrm{side opposite to angle A}}{Hypotenuse}\\\sin A =\frac{a}{b}

∴ \sin A = \frac{a}{b}
