Step-by-step explanation:

Sum of interior angles of a polygon is given by (n-2)180°

where,n is the number of sides.

Since this polygon has 4 sides,

sum of the interior angles = (4-2)180°=360°

x+115°+95°+70°=360°

x°=360°-280°

= 80°

Answer:

x = 80

Step-by-step explanation:

In a quadrilatoral the interior angle sum always adds up to 360 degrees so to find x you would add all of the interior angle sums and subtract that from 360

115 + 95 + 70 + x = 360     just add the like terms

280 + x = 360                 now subtract 280 from both sides so x is alone and you can figure out its value

x= 80

Solve 5(r—1)=2(r-4)-6 step by step
frozen [14]

Answer:

r = -3

Step-by-step explanation:

Performing the indicated multiplication on both sides of this equation, we get:

5r - 5 = 2r - 8 - 6

Combining the r terms:  3r - 5 = - 8 - 6.

Combining the constants:  3r = 5 - 14, or 3r = -9.

Dividing both sides by 3, to isolate r, we get:  r = -3

The label on the car's antifreeze container claims to protect the car between −30°C and 130°C. To covert Celsius temperature to
jonny [76]

Answer:

-22°F < x < 266°F.

Step-by-step explanation:

The question states the incorrect formula to convert the Celsius temperature (C) into the Fahrenheit temperature (F). The correct one is given by:

F = 9C/5 + 32.

The given temperature inequality in Celsius is:

-30°C < x < 130°C; where x is any number that satisfies the inequality.

To convert it into Fahrenheit, simply plug in the values in the above formula.

Lower Limit:

F = 9(-30)/5 + 32.

F = -54 + 32.

F = -22°F.

Upper Limit:

F = 9(130)/5 + 32.

F = 234 + 32.

F = 266°F.

Therefore, the inequality will be -22°F < x < 266°F!!!
