The angles of a triangle are 2x, 3x and 7x respectively. If the sum of the angles of a triangle is 180°What is the measure of ea
vodomira [7]

Answer:

30°, 45°, and 105°

Step-by-step explanation:

Find the value of x

2x + 3x+ 7x = 180

12x = 180

x = 180/12

x=15

Get the value of the angles

2x = 2(15)

3x= 3(15)

7x= 7(15)

The measure of the angles are 30°, 45°, and 105° respectively.

Find the difference: 7 7/8 - 3 1/4
DIA [1.3K]
In order to subtract mixed fractions, we must convert them into improper fractions first. To do this simply multiply the whole number by the denominator and add the numerator. The product of this operation will be the new numerator (the whole number is no longer present).

(56 + 7)/8 - (12 + 1)/4
= 63/8 - 13/4

Now that we have our fractions in improper form, we must find the least common denominator which is 8. To avoid changing the value of the second fraction, multiply both the numerator and denominator by 2 (which is essentially 2/2 which equals to 1).

63/8 - 26/8
= 37/8

Make x the subject please
Sauron [17]
Y^2 = (2x+1)/(x-1)
xy^2-y^2 = 2x + 1
xy^2 - 2x = y^2 + 1
x(y^2 - 2) = y^2 + 1
x = (y^2 + 1) / (y^2 - 2)

Mrac [35]

Answer:

(15, 13)

Step-by-step explanation:

Midpoint is the half of the segment.

What I did to solve this was adding the two xs together to get 30 then find the average of 30 by dividing it by 2. This would give you 15

I did the same thing with the ys and got 13

hope this made sense
