sin 45 = opp/hyp
sin 45 = 4 / y
y = 4/sin 45
y = 4 /((sqrt2)/2)=4* sqrt(2)
tan 45 =opp/adj
tan 45 = 4/(x-3)
1 = 4/(x-3)
x-3 = 4
x=7
B
<h3><u>
Answer:</u></h3>
- Your answer would be "30".
<h3><u>
Step-by-step explanation:</u></h3>
- 2x + 20 = 3x - 10 [Corresponding Angles]
- => 10 + 20 = 3x - 2x
- => 30 = x
<h3><u>Conclusion:</u></h3>
Therefore, your answer would be "30".
Hoped this helped.

So you know that 30 + 30 + w + w = P. We also know the area is 240 square feet. Divide 240 by 30 to find the width of the area. 240 / 30 = 8. w = 8. So add 30 + 30 + 8 + 8 to find that P = 76. HOWEVER, remember that George is using part of his house as a wall instead of a fence. So subtract 8 from 76 to get 68 ft. George will need 68 ft. of fencing for his dog run.
