Answer:
156.37°
Step-by-step explanation:
We solve this above question, using Cosine rule which is given as:
Cos C = a² + b² - c²/2ab
Let the Angle be represented as: x
Cos x = 310² + 200² - 150²/2 × 310 × 200
x = arc cos [ 310² + 200² - 150²/2 × 310 × 200]
x = 23.63°
The angle, in degrees, that he must turn through to head straight for Island B is given as:
180° - 23.63°
= 156.37°
Answer:
just for some points answer is -1 and 1 for y and x respectively
The properties 1‚ 2‚ 4‚ and 5. are used

Answer:
a
Step-by-step explanation:
if the top angle is 90° then the traingle is an isosceles triangle.
meaning that a=b.
this specific traingle is a silver traingle meaning that the ratio of the sides is 1:1:the root of 2.
so if

is 'a' multiplied by the root of two we need to divise it by the root of two to get 'a' and a=b.
