Step-by-step explanation:
Answer:
The answer to your question is:
x = 18
m∠ABD = 36°
m∠DBC = 54°
Step-by-step explanation:
m∠ABD + m∠DBC = 90°
2x + 3x = 90°
5x = 90°
x = 90/5
x = 18
m∠ABD = 2(18)
= 36°
m∠DBC = 3(18)
= 54°
Answer: It’s D) 9x +6
Step-by-step explanation:
(3x+2)+2(3x+2)
you do distributive property
3x+2+6x+4
then combine like terms
= 9x+6
|7-10| = 3 (absolute value), then multiply to the negative sign. answer:-3
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°
