Answer:
10.3 units
Step-by-step explanation:
Recall: SOHCAHTOA
Reference angle = 69°
Side length Opposite to reference angle = x
Hypotenuse length = 11
Thus, apply the trigonometric ratio, SOH:
Sin 69 = Opp/Hyp
Substitute
Sin 69 = x/11
11 × Sin 69 = x
10.2693847 = x
x = 10.3 units (nearest tenth)

Hope this helps you. I apologize if it’s incorrect.
A) Angle 1 + Angle 2 = 180
B) Angle 1 - Angle 2 = 16
Adding both equations:
2 * Angle 1 = 196
Angle 1 = 98
Angle 2 = 82
D = sqrt (x2 - x1)^2 + (y2 - y1)^2
(1,-2)(10.-4)
d = sqrt (10 - 1)^2 + (-4 - (-2)^2
d = sqrt (9^2 + (-4 + 2)^2
d = sqrt (9^2 + (-2^2)
d = sqrt (81 + 4)
d = sqrt 85
d = 9.2
D(t)=25(0.82)^t
d(4)=11.3mg
