Find the measures of the interior angles of the triangle.
Sauron [17]

Answer:

x = 88

The measurement of the other unknown angle is = 44°

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180°

48 + x + x - 44 = 180 add like terms

4 + 2x = 180 subtract 4 from both sides

2x = 176 divide both sides by 2

x = 88

Now to find the measure of two other angles we replace x with 88

Nember 1: 2/7 as decimal
MariettaO [177]

Answer:

Number 1: <em>0.28571428571429</em>

Number 2: <em>2.1666666666667</em>

Number 3: <em>0.1875</em>

Number 4: <em>0.75</em>

Number 5: 0.5

Number 6: <em>13.875</em>

Number 7: <em>8.66666666667</em>

Number 8: <em>0.625</em>

Step-by-step explanation:

To get decimal

You have to divide numarator with denominator

2 : 7

5/10 = 5:10 = 0.5

When you have mixed number you have to multiply number not fraction with denominator and then add numarator

2 1/6 = 12 + 1 / 6 = 13/6 = 13 : 6 = 2.1666667

2x6 + 1

It doesn't matter how many numbers you'll add. At the end of the Number is best to add this

_

6

It means that number is repeating. You can still round it tho :-)

We can also say that

6

-- is same as 6:12

12

Solutions:

2/7 = 2:7 = 0.28571428571429

2 1/6 = 12 + 1 / 6 = 13/6 = 13 : 6 = 2.1666667

2x6 + 1

3/16 = 3 : 16 = 0.1875

3/ 4 = 3 : 4 = 0.75

5/10 = 5 : 10 = 0.5

13 7/8 = 104 + 7/8 = 111/8 = 111 : 8 = 13.875

13 x 8

8 10/15 = 120 + 10/15 = 130/15 = 130 : 15 = 8.66667

5/8 = 5:8 = 0.625

Maybe it can seems hard but it's pretty easy! I hope you will read whole explanation :-)

Have a nice day!
