Answer:
Step-by-step explanation:
Alright, lets get started.
using Sine Law,
Another angle will be
considering angle B, angle C = 
considering angle B', angle C' = 
Similarly, finding c'
Hence two triangles are possible with below details: : Answer
A = 30, B = 48.6, C = 101.4, c = 7.84
A = 30, B' = 131.4, C' = 18.6, c' = 2.55
Hope it will help :)
(2x^2 -5y)/(3x-y)
((2*2)^2-(5*-4))/((3*-4)-(-4))
(4^2+20)/(-12+4)
36/-8
-4.5
Answer:
4 + x =5
Step-by-step explanation:
By adding a variable you can set up an addition sentence
Answer:
a = 50°, b = 130°, c = 20°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles in the right triangle
a + 40° + 90° = 180°
a + 130° = 180° ( subtract 130° from both sides )
a = 50°
a and b are adjacent angles and sum to 180° , so
a + b = 180°
50° + b = 180° ( subtract 50° from both sides )
b = 130°
Then sum the angles in the top triangle, that is
30° + 130° + c = 180°
160° + c = 180° ( subtract 160° from both sides )
c = 20°
The answer is pro blah 48
