You’re answer is 21
7(3)= 21 I hope I’m right :))
The angles opposite equal sides are also equal. The sum of angles in a triangle is 180. So 2x + 27 + 2x + 27 + 3x + 28 = 180.
7x + 82 = 180
7x = 98
x = 14
Now plug x into each angle to find their measures.
Answer:
sin(x) and cos(y) are equal and have ratio of 1 : 1
First find the missing hypotenuse using Pythagoras theorem:
a² + b² = c²
12² + 5² = c²
c = √144+25
c = 13
using sine rule:


using cosine rule:


Answer:
C=7
Step-by-step explanation:
Because it's a right angle in total we know the 2 expressions combined will equal 90.
(8c-5)+(6c-3)=90
