X is 50 because a triangle should end up being equal to 180 in total and since the top is 80 then that leaves you with 100 and then the two bottoms are the same so that makes it 50

Answer:

x = 50

Step-by-step explanation:

The base angles of an isosceles triangle are the same

The unmarked angle is also x

The sum of the angles of a triangle is 180

x+x+ 80 = 180

2x+80 =180

Subtract 80 from each side

2x+80-80 = 180-80

2x = 100

Divide by 2

2x/2 = 100/2

x = 50

The answer is $2 \frac{1}{6}$ .

Explanation:

In order to subtract the fractions, we must make them like fractions. To do this, the denominators must be the same by multiplying (only). Since the first fraction is $\frac{10}{3}$ , 3 can be multiplied by 2 to get 6, which is the other fraction, we can multiply it. Whatever you do to the denominator you must do to the numerator. Now multiply 2 by the numerator (10) to get $\frac{20}{6}$ . Now we can subtract the fractions $\frac{20}{6}$ and $\frac{7}{6}$ to get 13/6. Since this fraction is not in mixed fraction form yet, we must do that first. goes into 13 twice, so the whole number is 2 and there is still 1 left, making the fraction $\frac{1}{6}$ . Therefore, the difference is 2 $\frac{1}{6}$ .

On a number line, suppose point E has a coordinate of −2, and EG=7. What are the possible coordinates of point G? The possibl

laila [671]

Answer:

-9 ; 5

Step-by-step explanation:

Given that:

Coordinate of Point E = - 2

EG = 7

Possible coordinate of G

On the number line, G may be located on either side of E

If G is to the left of E; the coordinate if G is expressed as : (E - EG) = (-2 - 7) = - 9

If G is to the right of E; the coordinate if G is expressed as : (E + EG) = (-2 + 7) = 5

Hence, the possible coordinates of G are :

-9 and 5
