Answer:
Step-by-step explanation:
The surface area of a rectangle can be calculated with:
The surface area of a trapezoid can be calculated with:
Calculate the area of the base, wich is a rectangle:
There are two equal rectangles, therefore, multiply the area of any of them by 2:
Calculate the area of the other rectangle:
There are two equal trapezoids, therefore, multiply the area of any of them by 2:
Therefore, the surface area will be the sum of all the areas calculated:
The measure of the angle B is 30 degree after applying the sin law of triangle.
<h3>What is the triangle?</h3>
The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have a triangle shown in the picture:
We can apply the sin law of the triangle to find the angle B
SinB = 0.499
B = 29.99 ≈ 30 degree
Thus, the measure of the angle B is 30 degree after applying the sin law of triangle.
