Answer:
X=1 and Y=1 in the first question
Step-by-step explanation:
simply 12X means 12*x, so x=1 and 12*1+3*1=15 question 1
and question 2
2X means 2*X x=8 so 2*8=16 so 16-3 because Y=1 and
16-3=13

Answer:
elga is 32 and alvin is 49
5. We can see that angle a is the same angle as the 130° angle, since they form a Z. The same goes for b and 65°. a° = 130°, b° = 65°
6. With the same Z angles, b° = 56°. Because the angles are parallel, a° = 124°
7. Because the angles are parallel, b° = 83°, and a° = 132°
8. Because the angles are Z angles, a° = 74°. Because a° and b° are supplementary angles, b° = 180° - 74° = 106°. Because c° and 74° are supplementary angles, c° = 180° - 74° = 106°. Because d° and 65° are parallel angles, d° = 65°. Because d° and e° are opposite angles, e° = 65°
