Answer:
62
Step-by-step explanation:
2y-5 and 95 are vertical angles so they are equal



3x and 144 form a linear pair angle so



x=12 and y=50 so

3 * N = 1
The multiplicative inverse is just the reciprocal of the number. The reciprocal is just " flipping " the number. So the reciprocal of 3 (or 3/1) is 1/3. And any time u multiply a number by its multiplicative inverse (reciprocal), the result is 1
3 * 1/3 = 3/3 = 1.....so N is ur multiplicative inverse
Answer: 140
Step-by-step explanation: 25x20=500
32x20=640
640-500= 140!!
Complementary angles are two angles that add up to 90°
Supplementary angles are two angles that add up to 180°
Vertical angles are two angles that are opposite of each other and are also congruent
