C is the correct answer to this question :)
Answer:
Given an exponential function of the form
y = a*(b)^x
The values of b that will result in the desired percentage values are:
Case 1
b = 23% decrease
1 - 0.23 = 0.77
y = a*(0.77)^x
Case 2
b = 8% increase
1 + 0.08 = 1.08
y = a*(1.08)^x
Case 3
b = 15% decrease
1 - 0.15= 0.85
y = a*(0.85)^x
Case 4
b = 120% increase
1 + 1.2 = 2.2
y = a*(2.2)^x

Answer: The measurements of the two angles are 60° and 80°.
Step-by-step explanation:
A quadrilateral is a shape that has four sides and the total angle is 360°. Two angles of a quadrilateral measure 140° and 80°.
This means the two angles have a total of (140° + 80°) = 220°. We can then subtract from 360° to know the value of the other remaining angles. This will be:
= 360° - 220°
= 140°
The other two angles are in the ratio of 3:4. This means the angles are:
(3/3+4) × 140° = 3/7 × 140° = 60°
(4/3+4) × 140° = 4/7 × 140° = 80°
The measurements of the two angles are 60° and 80°.
