Answer:
In triangle SHD and triangle STD.
[Side]
Since, a line is said to be perpendicular to another line if the two lines intersect at a right angle.
⇒
[leg] [Given]
Reflexive property states that the value is equal to itself.
[Leg] [Reflexive property]
HL(Hypotenuse-leg) theorem states that any two right triangles that have a congruent hypotenuse and a corresponding congruent leg are the congruent triangles.
then, by HL theorem;
Proved!
The area of a triangle is 1/2 bh
so to find the area of the larger triangle do the following calculation:
1/2 time 12 time 7. that will give you 42 ft squared. that is the larger triangle.
the next way to find the area i will show you is:
pretend that the the triangle is inside of a rectangle. now you have 4 triangles. you know that the base of the rectangle is 15 ft anf the height is 7. now take the smaller triangle and it has its rectangle base 3 and height 7. multiply to get 21 feet squared. divide by 2 since there are 2 triangles in the small rectangle. 10.5 feet squared
You multiply 39.90 x 6 then divide by 100. You subtract the answer, 2.39 of the original price. Then you multiply it to her 187.55
For this case, the first thing you should do is observe the solution set.
We have then that the set of solution is given by:
(-inf, -4) U [3, inf)
Therefore, we have:
For (-inf, -4):
x <-4
For [3, inf):
x ≥ 3
Thus, the inequality in the graph is:
x <-4 and x ≥ 3
Answer:
x <-4 and x ≥ 3
Divide 14/18 then divide 16/20. 14 divided 18 is .777 while 16 divided by 20 is .80. Therefore Trey did better.
