Answer:
Option (D) is correct.
Step-by-step explanation:
In a triangle BCD , with b, c, d as the sides of triangle.
Sine rule states when we we divide side b by the sine of angle B then it is equal to side c divided by the sine of angle C and also equal to side d divided by the sine of angle D.
Using Sine rule,

Consider the first and third ratio,

Substitute the values of d = 3 , b= 5 and ∠D=25°

Thus, Measure of angle B is 45 and 135 as sinB is positive is first and 2nd quadrant.
Thus, option (D) is correct.
Answer:
Option "D" is the correct answer to the following question.
Step-by-step explanation:
Given:
Length of painting = 25 inch
Height of painting = 16 inch
Width of frame = w inch
Find:
Area of Picture with frame
Computation:
New length of painting = 25 + w + w
New length of painting = 25 + 2w inch
New height of painting = 16 + w + w
New height of painting = 16 + 2w
Area = l x b
So,
Area of Picture with frame = [25 + 2w][16 + 2w]
Area of Picture with frame = 400 + 50w + 32w + 4w²
Area of Picture with frame = 4w² + 82w + 400
