Answer: Your answer would be 45

Step-by-step explanation:

That triangle appears to be an isosceles which means there are two sides that are the same length which would make the the missing angles the same degree and a triangles angles added together should equal 180° so 45+45= 90 and 90+90=180

Solve by using the quadratic formula.<br> 3psquared+7p+2=0

Rainbow [258]

Answer:

$\large\boxed{x=-2\ or\ x=-\dfrac{1}{3}}$

Step-by-step explanation:

The quadratic formula of a quadratic equation

$ax^2+bx+c=0\\\\x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

We have the equation:

$3p^2+7p+2=0\to a=3,\ b=7,\ c=2$

Substitute:

$b^2-4ac=7^2-4(3)(2)=49-24=25\\\\\sqrt{b^2-4ac}=\sqrt{25}=5\\\\x_1=\dfrac{-7-5}{2(3)}=\dfrac{-12}{6}=-2\\\\x_2=\dfrac{-7+5}{2(3)}=\dfrac{-2}{6}=-\dfrac{1}{3}$
