That is so hard why u I understand how u feel

Answer: x= 14

Step-by-step explanation: look at transversal ED. Angle E and angle D are alternate interior angles of this transversal. Alternate interior angles are equal. Now we need to find angle measure of D to solve. The triangle angle sum theorem states that all interior angles of a triangle sum to 180 degrees. 50+ 48 + D =180.

Measure of angle D is 82. Now that we have the two alternate interior angles, we set them equal to each other to solve.

6x-2= 82. Add 2 to both sides. 6x = 84. Divide both sides by 6. X =14

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°

C

85% of what number is 17

Answers

Answer:

20

Step-by-step explanation:

To solve this problem, we must first assign a variable, x. Now, converting the words into a math equation, we get:

85% * x = 17.

Soliving the linear equation, we get:

0.85x = 17.

So, x = 20.

Hence, our answer is 20.
