$~~~\text{Area of triangle} = \dfrac 12 \times \text{Base} \times \text{Height}\\\\\implies 10 = \dfrac 12 \times 5 \times w\\\\\implies w =\dfrac{20}5 \\\\\implies w = 4 ~cm$

Can someone tell me how to do this? with steps?

MrRa [10]

Answer:

Step-by-step explanation:

In Δ AFB,

∠AFB + ∠ABF + ∠A = 180 {Angle sum property of triangle}

90 + 48 + ∠1 = 180

138 + ∠1 = 180

∠1 = 180 - 138

∠1 = 42°

FC // ED and FD is transversal

So, ∠CFD ≅∠EDF {Alternate interior angles are congruent}

∠2 = 39°

In ΔFCD,

∠2 + ∠3 + ∠FCD = 180

39 + ∠3 + 90 = 180

129 +∠3 = 180

∠3 = 180- 129

∠3 = 51°

How to find cp if loss and sp are given

velikii [3]

Step-by-step explanation:

$\tt{ \: H \: E \: Y \: \: T \: H \: E \: R\: E \: }$ !

When Loss and Selling price ( SP ) are given , Cost price ( CP ) can be found out using the following formulae :

✰ $\large{ \boxed{ \boxed{ \tt{CP = Loss + SP}}}}$

$\text{How \: did\: we \:get \:the \: formula : \: CP \: = Loss \: + \: SP} \:$ ?

We simply derived the formula from Loss = CP - SP.

First , Swap the sides of the equation :

⟶ $\text{CP - SP = Loss}$

Move SP to right hand side and change it's sign :

⟶ $\text{CP = Loss + SP}$

This is how , CP can be obtained when we are given loss and SP.

Hope I helped ! ♡

Have a wonderful day / night ! ツ

PLEASE ANSWERRRRRRRRRRRRR

Sunny_sXe [5.5K]

Answer:

y = 23x-82

Step-by-step explanation:

The equation is written in the form y = mx+b

We need to find the slope

m = (y2-y1)/(x2-x1)

= (79-56)/(7-6)

= 23/1

The slope is 23

y= 23x +b

Put in a point for x and y to determine b

10 =23(4) +b

10 =92 +b

Subtract 92 from each side

10-92 = 92-92 +b

-82 =b

The equation is

y = 23x-82
