Answer:
x = 12
m(QS) = 52°
m(PD) = 152°
Step-by-step explanation:
Recall: Angle formed by two secants outside a circle = ½(the difference of the intercepted arcs)
Thus:
m<R = ½[m(PD) - m(QS)]
50° = ½[(12x + 8) - (4x + 4)] => substitution
Solve for x
Multiply both sides by 2
2*50 = (12x + 8) - (4x + 4)
100 = (12x + 8) - (4x + 4)
100 = 12x + 8 - 4x - 4 (distributive property)
Add like terms
100 = 8x + 4
100 - 4 = 8x
96 = 8x
96/8 = x
12 = x
x = 12
✔️m(QS) = 4x + 4 = 4(12) + 4 = 52°
✔️m(PD) = 12x + 8 = 12(12) + 8 = 152°
Answer:
1 1/8
Step-by-step explanation:
First, Make the first fraction into a new one with an equal denominator. (3/4 x2= 6/8)
Then, subtract the whole numbers (2-1=1) and the fractions (6/8-5/8= 1/8)
Lastly, add your two differences together and you get 1 1/8.
Answer:
2x
Step-by-step explanation:
x and 2 are common to both 10x and 22x, so 10x + 22x = 2x(5 + 11)
The GCF is 2x.
