To solve this, all you have to do is plug in the 14 where the x value is:
y=1.65(14) +2.35 which equals 25.45
Sin(theta) = O/H = 5/16 (this us the ratio)
If we go further for the problem:
sin(theta) = 5/16 becomes sin-1 (5/16) = 18.2°
Good luck!
Let ABC be the triangle (with A as summit) and BC its base which is at the same time the diameter of the semi-circle. Let AH be the altitude of ABC.
Length of the Base BC (which is also the diameter of the semi circle) = 4 units and consequently the radius = 2 units
Length of the altitude AH = 5 units, hence:
a) the Area of ABC = (Base x Altitude)/2 = (4 x 5)/2 = 10 units²
b) the area of the semi circle is: (π x R²)/2 = (π x 2²)/2 = 6.28 units²
Total area = 16.28 units²
It would be e cause it needs to be
Hope the shown work helps you!!
