Answer:
∠G = 23.3
∠H = 42.8
∠J = 19.9
Step-by-step explanation:
<em>Tan(G) = 0.43</em>
=> G = Tan⁻¹(0.43)
=> <u>∠G = 23.3</u>
<em>Sin(H) = 0.68</em>
=> H = Sin⁻¹(0.68)
=> <u>∠H = 42.8</u>
<em>Cos(J) = 0.94 </em>
=> J = Cos⁻¹(0.94)
=> <u>∠J = 19.9</u>
Hope this helps!
I don't understand. Could you perhaps be a little bit more clear?
Answer:
Step-by-step explanation:
Let x represent the width. Since the length is 3 more than 4 times the width, that would be equal to 3+4x. The perimeter is the sum of all sides, so that would be x+x+3+4x+3+4=86. Combine like terms, which would result in 10x+6=86. Subtract 6 from both sides giving you 10x=80. Divide by 10 giving you x=8. That means that the width is 8. The length is 3+4x. Substitute 8 for x giving you 3+4(8). Multiply, giving you 3+32, then add, which would give you 35. 35 is the length.
