Let the largest angle in a triangle be x .
Then :-
The smallest angle :-

The third angle :-

Let us find the measure of the three angles .
Sum of all angles in the interior of a triangle = 180°
An equation to find the value of each angle :-








Which means :-
Measure of the largest angle = 90°
Measure of the smallest angle :-


Measure of the third angle :-


<h3>Therefore :-</h3>
The measure of the largest angle = 90°
The measure of the smallest angle = 30°
The measure of the third angle = 60°
Answer:
1,4.560
Step-by-step explanation:
I am not so sure.
Let
x---------> <span>the width of the gravel path
we know that
72=(2x+6)*(2x+7)----> 72=4x</span>²+14x+12x+42-------> 4x²+26x-30=0
using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
x=1
the answer is
the width of the gravel path is 1 ft
-4
It is the point where the line touches the y-axis
V = 1/3 l h w
V = 1/3 (12)(15)(9)
V= = 540
answer 540 m^3
