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
5. answer is E
why?
a- does not show him stopping it cannot be this
b- also does not show him stopping
c- he is slowing down, stopping, and speeding up after stopping which means he doesn't automatically stop this is not the answer
d- it is said he waits so he doesn't just stop and speed up again this cannot be the answer
E. shows a slowing down a stop and a speeding up this is the answer
6. 62 ft tall tree
scale 4in=28 ft
how tall is it in scale
simplify scale to 1in=??
÷4 both
1in=7ft
now 62÷7 will give you the answer 8.85 or 9in
ANSWER is A
7. 4x-2>10
solve for X
+2 both sides
4x>12
÷4 both sides
x>3
The circle must be on 3 a and b are not the answer
x is GREATER THAN the line goes to the right c is not the answer
the solution is only greater than not greater than or equal to.. the circle is open
d is not the answer
E is the answer
Answer:
The Answer is X= 17.1 in.
Step-by-step explanation:
The answer is letter C. (x<span>, </span>y) → (–x, –y<span>) </span>
