Answer:
sin© = 3/5
Cos© = 4/5
Tan© = 3/4
Explanation:
The opposite (opp) side of the right angle triangle is the side facing the angle ©
The hypothenus (hyp) side is the longest side,
The adjacent (adj) side is the third side.
sin© = opp/hyp
Cos© = adj/hyp
Tan© = opp/adj
Answer: 300
Step-by-step explanation: 300+200=500
then 500-200=300
Answer:
A. 4.4 units²
Step-by-step explanation:
Area of a Triangle: A = 1/2bh
sin∅ = opposite/hypotenuse
cos∅ = adjacent/hypotenuse
Step 1: Draw the altitude down the center of the triangle
- We should get a perpendicular bisector that creates 90° ∠ and JM = KM
- We should also see that we use sin∅ to find the <em>h</em> height of the triangle and that we use cos∅ to find length of JM to find <em>b</em> base of the triangle
Step 2: Find <em>h</em>
sin70° = h/3.7
3.7sin70° = h
h = 3.47686
Step 3: Find <em>b</em>
cos70° = JM/3.7
3.7cos70° = JM
JM = 1.26547
Step 4: Find entire length base JK
JM + KM = JK
JM = KM (Definition of Perpendicular bisector)
2(JM) = JK
2(1.26547) = 2.53095
b = 2.53095
Step 5: Find area
A = 1/2(3.47686)(2.53095)
A = 4.39988
A ≈ 4.4
Answer:
D. x = 21
Step-by-step explanation:
x - 4= 17
Step 1: Add 4 to both sides
x - 4= 17
<u> +4 +4</u>
x = 21
