Answer:
x = 63°
Step-by-step explanation:
See the attachment
The measure of the angles in a triangle = 180 . If the sides of a triangle are congruent, then the base angles are equal. So in the triangle with the 72°, you have another angles = 72°. Looking at the same triangle, 72° + 72° + part of the right angle = 180°. Do the math! 72° + 72° = 140°; 180° -144° = 36° (this is the measure of the piece of the right angle that is in the triangle with the 72° angle.. So the other part of the 90°(right angle) = 90° - 36° = 54°.
Now to solve for x: You know that if the sides are congruent in a triangle, then the base angles are equal. Thus this triangle angles are x, x, and 54°.
You know that a triangle = 180°, so x + x + 54° = 180°; 2x +54° = 180°; 2x = 126°; x = 63°
1.) Adrianna has 10 pieces of gum.
2.) She now buys 3 MORE pieces of gum.
3.) 10 (original amount) + 3 (amount bought) = 13 pieces of gum
4.) Adrianna now has 13 pieces of gum to share with her friends.
The 35% is 81.90 plus the 234. So your answer would be $315.90 is the original price. If you need me to explain it let me know :)
