The smallest angle in a triangle is 1/3 as large as the largest angle. The third angle is twice the smallest angle. Find the thr

Sliva [168]

Let the largest angle in a triangle be x .

Then :-

The smallest angle :-

$\frac{1}{3} x$

The third angle :-

$\frac{2}{3} x$

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 :-

$x + \frac{1}{3} x + \frac{2}{3} x = 180$

$x + \frac{3}{3} x = 180$

$x + \frac{1}{1} x = 180$

$x + 1x = 180$

$x + x = 180$

$2x = 180$

$x = \frac{180}{2}$

$x = 90$

Which means :-

Measure of the largest angle = 90°

Measure of the smallest angle :-

$\frac{1}{3} \times 90$

$= 30°$

Measure of the third angle :-

$\frac{2}{3} \times 90$

$= 60°$

<h3>Therefore :-</h3>

The measure of the largest angle = 90°

The measure of the smallest angle = 30°

The measure of the third angle = 60°

If the Revenue for the week is $2000, and labor cost consists of two workers earning $8 per hour who work 40 hours each, what is

Advocard [28]

2 workers 8 dollars per hour and 40 hours
mutiply
2*8*40=640 dollars

now costlabor/revenue (try to get to percent which is parts out of 100 so x%=x/100)
640/2000
64/200
32/100=32%

answer is 32%

A grasshopper jumps from the ground. The path of the grasshopper is modeled by the equation y=−0.5x2+8x where x is the horizonta

Marysya12 [62]

Please use " ^ " to indicate exponentiation: <span>y=−0.5x^2+8x

Examining this function, we see that its graph is a vertical parabola opening down.

You did not supply instructions for this problem.
However, one could guess that you might want to find the highest point of the grasshopper's path. To do this, find the vertex: Find the x value defined by

x = -b/(2a). Here, a= -0.5 and b= 8. Thus, the vertex is at x = -8/(2[-0.5]), or

x -8/(-1) = 8 units. The corresponding y value is then

y = </span><span>−0.5*8^2+8(8) = -0.5(64) + 64, or 32 units.</span>
