#1 Find each angle measure in the triangle. 3x⁰ 2x° 4x° The measure of the angle labeled 2xº angle labeled 3x° is Previous K °.
julia-pushkina [17]

3x° is 60° , 2x° is 40° and 4x° is 80°

<h3>How to determine the angles</h3>

Note that the sum of angles in a triangle is 180°

Solve for x in the triangle

Then,

3x° +2x° + 4x° = 180°

Add the x°

9x° = 180°

Divide both sides by 9

x° = 180÷ 9 = 20°

If x° = 20

Then 3x° = 3× 20 = 60°

2x° = 2 × 20 = 40°

4x°= 4× 20 = 80°

Therefore, 3x° is 60° , 2x° is 40° and 4x° is 80°

The height, h, in meters above the ground, of a projectile at any time, t, in seconds, after the launch is defined by the functi
Ivanshal [37]
The equation h(t) =-6t^2 + 15t + 2 <span>sets the parabola. You can find the parabola vertex as:
</span>
t_v= \frac{-b}{2a} =- \frac{15}{2\cdot (-6)} = \frac{15}{12}= \frac{5}{4}=1.25

then 

h( \frac{5}{4} )=-6\cdot  (\frac{5}{4} )^2+15\cdot \frac{5}{4} +2= \frac{91}{8} =11.375

This means that the maximum height is 11.375 m and <span>a projectilereaches this height at 1.25 seconds.</span><span /><span>

4/x-3+5=2<br> What is the solution
Dmitry [639]

Answer:

x=\frac{5}{3}

Step-by-step explanation:

Let do algebra and figure out the value of x:

\frac{4}{x-3}+5=2\\\frac{4}{x-3}=2-5\\\frac{4}{x-3}=-3\\4=-3(x-3)\\4=-3x+9\\3x=9-4\\3x=5\\x=\frac{5}{3}

<u>Note:</u> assuming that the problem is \frac{4}{x-3}+5=2
