Answer:
B=48, A=106
Step-by-step explanation:
Using A and B as the unknown variables, not the point names.
The lines in the angles of B and D mean that those angles are congruent, or the same. B=D, so B=48. The lines are the same length, as marked with the arrows, which leads to unknown variable A=106, like point A shows.
Yes, because 90+90 adds up to 180 which is supplementary
The answer is: x = -1, y = +4
Answer:
127
Step-by-step explanation:
m<PQR and m<RQS are supplementary angles so their sum is 180
3x - 5 + x + 1 = 180 add like terms
4x - 4 = 180 subtract 4 from both sides
4x = 176 divide both sides by 4
x = 44
m<PQR is 3x - 5 replace x with 44
3*44 - 5 = 127
