Area of a triangle = (1/2)*base*height
For both of the triangles, you have the base (8.8 for the triangle on the left, 7.6 for the triangle on the right) and the side lengths, but not the height. But since both are isosceles triangles, you can find the height using the pythagorean theorem.
5.
First divide the triangle vertically into two triangles (see attached picture). Now you have two right triangles, you can apply the pythagorean theorem on either one of them to find the height. The pythagorean theorem says that for a right triangle,
, where c is the hypotenuse and a and b are the sides of the triangle.
Substituting the given values and rounding to nearest tenth:

Now that you have the height, you can find the area of the entire triangle.
A = (1/2)*base*height
A = (1/2)*8.8*9.0 = 39.6
6.
Same procedure.

A = (1/2)*base*height
A = (1/2)*7.6*9.2 = 35.0
Number 3 is .4 i think just minus 1.2 - .8
Answer:
hope this is right
Step-by-step explanation:
The majority of 65 degrees and up has more days than the others. But, That could change because we do not know how many day of the 12 year were 0- 32, 33 - 45, 46 - 64, and 65 degrees and up.
Answer:
2 left out, with 333 boxes
Step-by-step explanation:
2000/6=333.333333 (
)
of 6 is 2. Therefore, there would be 333 boxes, with two left unboxed.
<span>1. 3x + y = -7
2. -2x + 4y = 0</span>
1. y=-7-3x
2. -2x+4(7-3x)=0
2. -2x+28-12x=0
2. -14x=-28
2. x=2
1. y= -7-3*2
1. y = -13
