The angle of x is 71°
Because the triangle in isosceles the two bottom angles will have the same measure.
The angles of a triangle will add to 180° so you subtract 38 and divide by 2.
Answer:
The answer is below
Step-by-step explanation:
a) Let negative means the turtle position when descending and positive for going up. Therefore since the turtle was 850 meters below see level, it was at -850. It then moves 165 meters up, hence its new position is -685 meters (-850 + 165). Lastly it moves down 165 meters, hence its new position is -850 meters (-685 - 165)
b) The change in position is the sum of the movements = +165 - 165 = 0 meters.
Answers: height, "h", of a triangle: <span> h = 2A / (b₁ + b₂) .
___________________________________________________ </span>
Explanation:
__________________________________________________
The area of a triangle, "A", is equal to (1/2) * (b₁ + b₂) * h ;
or: A = (1/2) * (b₁ + b₂) * h
or: write as: A = [(b₁ + b₂) * h] / 2 ;
___________________________________________
in which: A = area of the triangle;
b₁ = length of one of the bases
of the triangle ("base 1");
b₂ = length of the other base
of the triangle ("base 2");
h = height of the triangle;
____________________________________________________
To find the height of the triangle, we rearrange the formula to solve for "h" (height); assuming that all the units are the same (e.g. feet, centimeters); if no "units" are given, then the assumption is that the units are all the same.
We can use the term "units" if desired, in such cases; in which the area, "A" is measured in "square units"; or "units²",
_________________________________
So, given our formula for the "Area, "A"; of a triangle:
_________________________________________________
A = [(b₁ + b₂) * h] / 2 ; we solve for "h" in terms of the other values; by isolating "h" (height) on one side of the equation.
If we knew the other values; we plug in the those other values.
______________________________________________
Given: A = [(b₁ + b₂) * h] / 2 ;
Multiply EACH side of the equation by "2" ;
_________________________________________
2*A = { [(b₁ + b₂) * h] / 2 } * 2 ;
_________________________________________
to get:
_________________________________________
2A = (b₁ + b₂) * h ;
_____________________________________________________
Now, divide EACH side of the equation by: "(b₁ + b₂)" ; to isolate "h"
on one side of the equation; and solve for "h" (height) in terms of the other values;
_____________________________________
2A / (b₁ + b₂) = [ (b₁ + b₂) * h ] / (b₁ + b₂);
______________________________________
to get:
_______________________________________________
2A / (b₁ + b₂) = h ; ↔<span> h = 2A / (b₁ + b₂) .
__________________________________________________</span>
Answer: No.
Step-by-step explanation:
9*7=63
63+7=70
70>73
Answer:
(2,-2)
Step-by-step explanation:
Point A is 2 units to the right of the origin so the x coordinate is 2
It is also 2 units down so the y coordinate is -2
The point is (x,y) so A = (2,-2)
