Hello!
Since the angles are alternate interior angles they equal each other
5x - 28 = 3x + 12
Now you solve this algebraically
5x - 28 = 3x + 12
Subtract 3x from both sides
2x - 28 = 12
Add 28 to both sides
2x = 40
Divide both sides by 2
x = 20
Now we put x into the equation we are wanting to find out
5x - 28
5(20) - 28
Multiply
100 - 28
Subtract
72
The answers are x = 20 and 5x - 28 = 72°
Hope this helps!
Answer: No
Step-by-step explanation: Complementary angles are those that add up to 90 degrees, 47 + 53 equals to 100.
Answer:
$1.26
$19.26
Step-by-step explanation:
Sales tax = 18(7%) = 18(7/100) = 1.26
Total cost = 18 + 1.26 = 19.26
Answer:
(x,y) = (19/2,-1/2)
Step-by-step explanation:
hope its correct!
Step-by-step explanation:
The given measurements are:
16 m, 21 m, 39 m
We know that, it is only possible to form a triangle if sum of the measures of any two lengths is always grater than the measure of third length.
Therefore, it is not possible to form a triangle with given measurements.
