Step-by-step explanation:
Answer:
∠ QPR = 125°
Step-by-step explanation:
the angles subtended by 2 congruent arcs are congruent , that is
5x = 4x + 25 ( subtract 4x from both sides )
x = 25
Then
∠ QPR = 4x + 25 = 4(25) + 25 = 100 + 25 = 125°
Answer:(0,4)
Step-by-step explanation:
4x+5y=20
4(0)+5y=20
5y=20
5x/5=20/5
y=4
4x+5(4)=20
4x+20=20
-20 -20
4x=0
4x/4=0/4
x=0
4x+5y=20
4(0)+5(4)=20
0+20=20
20=20
I think this is right
