Step-by-step explanation:
no
if X=1/7
then
7x=1
...........
Answer:
A. a=25
B. RCA and QBD
C. Angle PBA
Step-by-step explanation:
2a-9+5a+14=180 since they are same side interior they equal 180
combine like terms- 7a+5=180
subtract 5 from each side- 7a=175
divide 7 from each side- a=25

Eqn (1)*3: 15x + 6y = -9 -> Eqn (3)
Eqn (3) - Eqn (2): 12x = -15
x = -5/4 = -1 1/4
Eqn (2): -15/4 + 6y = 6
6y = 9 3/4
y = 1 5/8
x = -1 1/4
y= 1 5/8
The Sum of this question is.... -43.
-25 - 18 equals to -43.
Sin 28 = 3/AB
AB= 3/ sin 28
AB=6.4
