To answer this problem, you need to use SOHCAHTOA. The pole, the tent, and the ground form a right triangle. One leg is equal to 5. The top angle is 55. You need to find length of the other leg, so use tangent.
tan55=O/5
O=0.4375
Double this to find the total width of the tent. 0.4375*2=0.875
0.875 (rounds to 1) feet
Hope this helps!!
Answer:
A = 22.5 m²
Step-by-step explanation:
longest side length
b = √((-7 + 4)² + (-1 - 8)²) = √90
other sides
a = √((-1 + 7)² + (2 + 1)²) = √45
height
h = √((√45)² - (½√90)²) = √22.5
Area of triangle
A = ½bh = ½√90√22.5 = 22.5 m²
a little math shows that this triangle is a tilted half of a square with sides √45

Answer:
2. 2x² + 7x - 13
Step-by-step explanation:
3[x² - 1] - [x² - 7x + 10]
3x² - 3 - x² + 7x - 10
2x² - 13 + 7x
The above answer is a bit written in reverse, which is the exact same result.
So, after performing the Distributive Property, from there, you can combine all like-terms, as done above.
** Now, just in case you are wondering why that -7 has been altered to its opposite, it is because although -7x does not have another like-term to pair up with, IT IS STILL HOOKED UP TO ANOTHER NEGATIVE, so that -7x is REALLY 7x.
I am joyous to assist you anytime.
