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°
k = - 3
given k + 
= 
subtract from both sides of the equation
k = - = - 
= - 3
Answer:
2s + t = 23.5
Step-by-step explanation:
There are two types of shortboards:
Let the width of a standard shortboard be represented by s.
Similarly, Let the width of a technical shortboard be represented by t.
As per the given information: total width of two standard shortboards
and a technical shortboard is 23.5 inches.
Representing it as an equation in terms of the variables defined:
2s + t = 23.5
