Triangle $PQR$ is isosceles and the measure of angle $R$ is $40^\circ$. The possible measures of angle $P$ are $x,y,z$. What is

the value of the sum $x y z$
Mathematics

Answer:

The possible value for angle P will be 100

And sum will  also 100 because it has only one value.

Step-by-step explanation:

Given:

angle R measures 40 degree  and PQR is isosceles triangle.

To Find:

Measure angle P.

Solution:

The given triangle is isosceles hence it will have 2 same angle included in it.

And sum of all angles of a triangle is 180 degree.

let same angles be x and other be y

So ,

x+x+y=180.............. sum of all angles.

2x+y=180.

Now to find possible values for y ,with x=40,

2x+y=180

80+y=180

y=100

So being x= 40 y =100  which satisfy given angle R condition.

now let y=80,then x should satisfy 40 degree value, so

2x+80=180

2x=100

x=50

it doest not satisfy the given value hence possible for  y will be 100.

Since x=40 degree.

10(-3n + 8) = 380 pls find n
Flauer [41]

Answer:

n = - 10

Step-by-step explanation:

10(-3n + 8) = 380

-30n + 80 = 380

80 - 380 = 30n

30n = - 300

n = - 300 : 30

n = - 10

D) 10x + 5y = 10(6) + 5(9) = 60 + 45 = 105

Answer is (D)

15) 2 x 12 - 8 (divided by) 2^2
Exponent first: 2 x 12 - 8 divided by 4
Multiplication/ Division: 2 x 12 = 24 and -8 divided by 4 = -2
Add/Subtract: 24 - 2 = 22

If y varies directly as x, and y is 48 when x is 6, which expression can be used to find the value of y when x is 2?
sertanlavr [38]

y = ( 48 *2 ) / 6

Step-by-step explanation:

If y varies directly as x they are directly proportional, which means they relate to each other in the same way....

2 : y = 6: 48

what is y if x = 2?

The value of y can be found if you write it a two fracrions

2 : y = 6 : 48

2 / y = 6 / 48

cross multiply the fractions gives

6*y = 48 *2

divide left and right of the = sign by 6 gives the answer:

y = ( 48 *2 ) / 6

(if you solve it you get y = 12 but that was not the question).

Other method:

multiply left and right of the = sign by y

2 * y/y = y *6 / 48

6y / 48 = 2 * 1

multiply left and right of the = sign by 48

6y * 48/48 = ( 48 *2 )

6y = ( 48 *2 )

divide left and right of the = sign by 6

6/6* y = ( 48 *2 )/6

y = ( 48 *2 ) / 6

(if you solve it you get y = 12 but that was not the question).
