Answer:
Sin theta = 12/13
Step-by-step explanation:
From the question;
Cot theta = 5/12
Kindly recall;
Cot theta = 1/ tan theta
Hence, tan theta = 12/5
Mathematically
tan theta= opposite/adjacent
to get hypotenuse, we will use Pythagoras’ theorem which states that the square of the hypotenuse equals sum of the squares of the two other sides
let hypotenuse be h
h^2 = 12^2 + 5^2
h^2 = 144 + 25
h^2 = 169
h = √169
h = 13
But sine theta = opposite/ hypotenuse = 12/13
well, the triangle is an isosceles, so it twin sides, and the twin sides make twin angles, as we see by the tickmarks on A and C, meaning AB = BC.

Answer:
3) 162 ft² || 4) 38.25 mm²
Step-by-step explanation:
3)
area of triangle = 0.5 * base * height
= 0.5 * 27 * 12
= 162 ft²
4) area of triangle = 0.5 * base * height
= 0.5 * 8.5 * 9
= 38.25 mm²
