Write a division problem that has a two digit quotient that is greater than 40 but less than 50.
trasher [3.6K]

Let

x--------> Dividend

y-------> Divisor

Q-------> Quotient

we know that

\frac{x}{y} = Q

solve for x

x=Q*y

40 < Q < 50

Examples

example 1

Q=45\\ y=4

Find the value of x

x=45*4\\ x=180

A division problem is equal to

\frac{x}{y} =\frac{180}{4} \\\\ = 45

example 2

Q=42\\ y=10

Find the value of x

x=42*10\\ x=420

A division problem is equal to

\frac{x}{y} =\frac{420}{10} \\\\ = 42

Triangle XYZ, XY= 80, ZY= 64 XZ= 48 what is the cosine
SVETLANKA909090 [29]

Answer:

cos=\frac{4}{5}

Step-by-step explanation:

Cosine is the adjacent side over the hypotenuse (You can remember sin, cos, and tan by using sohcahtoa or sin = opposite/hypotenuse, cos = adjacent/hypotenuse, tan = opposite over adjacent). I think a picture would help, too.

I attached a picture of what I think the triangle would look like.

If the picture is right (we're assuming it is) and going with what we're given (the triangle was addressed as triangle XYZ, meaning that <u>angle Y is in the middle and that's the one we'll use</u>).

Looking at my picture then:

cos=\frac{64}{80} \\cos=\frac{8}{10} \\cos=\frac{4}{5} .

Determine the measure of angle A, B, and C in triangle ABC. If m∠A=(x-10)°,m∠B=(2x-50)°,and m∠C=x°
Effectus [21]

Answer:

m∠A = 50°

m∠B = 70°

m∠C = 60°

Step-by-step explanation:

Determine the measure of angle A, B, and C in triangle ABC. If m∠A=(x-10)°,m∠B=(2x-50)°,and m∠C=x°

In a Triangle, the sum of the interior angles of a triangle = 180°

Step 1

We solve for x

Hence:

m∠A + m∠B + m∠C= 180°

(x-10)°+ (2x-50)°+ x° = 180°

x - 10 + 2x - 50 + x = 180°

4x - 60 = 180°

4x = 180° + 60°

4x = 240°

x = 240°/4

x = 60°

Step 2

Solving for each measure

x = 60°

m∠A=(x-10)°

= 60° - 10°

= 50°

m∠B=(2x-50)°

= 2(60)° - 50°

= 120° - 50°

= 70°

m∠C=x°

= 60°
