Answer:
1
Step-by-step explanation:
once we know 2 of the angles we can find a third. once we have all 3 angles we only need one side length to tell us how big it is.
Bonus question: How many triangles can be drawn with one 3 inch side ,a 4 inch side, and a 20ºangle?
Answer:
Step-by-step explanation:
x is the length of the side opposite the reference angle of 32, and 10 is the side length adjacent to the reference angle. This satisfies the tangent ratio where
and solving for x:
x = 10tan32
Answer:
w = 5.2
Step-by-step explanation:
4(2.25w + 3.1) - 2.75w = 44.9
9w + 12.4 - 2.75w = 44.9
6.25w + 12.4 = 44.9
6.25w = 32.5
w = 5.2
