Answer:
The angle measures are;
36,72, 108 and 144
Step-by-step explanation:
Since it is a quadrilateral
the sum of all the interior angles is 360
so, we have that;
4x + x + 3x + 2x = 360
10x = 360
x = 360/10
x = 36
So each of the angles are as follows;
x = 36
4x = 4(36) = 144
3x = 3(36) = 108
2x = 2(36) = 72
We are given two sides and their included angle. Using the side-angle-side method we can find the Area of the triangle using the following formula:
Area = 0.5 ab sin(γ)
a = Measure of first side = 3.2 feet
b = Measure of second side = 4.7 feet
γ = Angle between the two sides = 62 degrees
Using the values in the above formula, we get:
Area = 0.5 x ( 3.2) x (4.7) x (sin(62))
Area = 6.64 square feet (rounded to nearest hundredth)
Thus, the Area of the given triangle is 6.64 square feet
It looks like

(If the limits are in the wrong order, just multiply the result by -1)
Split the integral at an arbitrary value between
