Answer:

34 degrees, 68 degrees, 78 degrees

Step-by-step explanation:

All angles in a triangle must add up to 180 degrees.

so

x + 2x + 2x + 10 = 180

(group together all the xs)

5x + 10 = 180

(subtract 10 from both sides)

5x = 170

(divide both sides by 5)

x = 170/5 = 34

Angle 1 = x

x = 34

Angle 1 = 34 degrees

Angle 2 = 2x

x = 34

(multiply both sides by 2)

2x = 68

Angle 2 = 68 degrees

Angle 3 = 2x + 10

x = 34

(multiply both sides by 2)

2x = 68

(add 10 to both sides)

2x + 10 = 68 + 10 = 78

Angle 3 = 78 degrees

CHECK YOUR ANSWERS:

All angles in a triangle must add up to be 180 degrees.

so

34 + 68 + 78 should equal 180

34 + 68 + 78 = 180 degrees

Hope this helps :)

Answer:

Step-by-step explanation:

sum of angles of a triangle= 180°

x+2x+2x+10=180

5x+10=180

5x=170

x=170/5

x=34

.:

x=34°

2x=34×2=68°

2x+10=2×34+10=68+10=78°

Please someone solve this problem <br>I really need answers ​

Answer:

x = 50°

y = 50°

z = 80°

Step-by-step explanation:

working out x:

angles on a straight line add up to 180°

x + 130° = 180°

subtract 130 on both sides

x = 180° - 130°

x = 50°

working out y:

two vertical lines means that both sides are equal, so both angles are also equal (it's an isosceles triangle). This means that y is the same angle as x = 50°

y = 50°

working out z:

the sum of a triangle add up to 180°

add up the angles of x and y and equate to 180°

50 + 50 + z = 180

100 + z = 180

subtract 100 on both sides

z = 180 - 100

z = 80°

Which unit rate is higher 24 for 5 or 5 for 24
frez [133]

Answer:

24 for 5 is higher because you have to divide 24 by 5 and if you do that it gives you $4.8, while 5 for 24 gives you a unit rate of $0.20.
