Answer:

Angle T= 36 degrees

Angle V= 54 degress

Step-by-step explanation:

okay so you know that this is a right angle and that all angles in a triangle add up to 180 degress

using that info,

you can say

2x+3x+90= 180

5x+90=180

5x= 180-90

5x= 90

x= 18

measure of angle T= 2x

2(18)= 36 degrees

measure of angle V= 3x

3(18)= 54 degrees

I hope this helps <3

$\displaystyle\iiint_{\mathcal E}xe^{x^2+y^2+z^2}\,\mathrm dV$
$=\displaystyle\int_{\varphi=0}^{\varphi=\pi/2}\int_{\theta=0}^{\theta=\pi/2}\int_{\rho=0}^{\rho=1}\rho\cos\theta\sin\varphi e^{\rho^2}\rho^2\sin\varphi\,\mathrm d\rho\,\mathrm d\theta\,\mathrm d\varphi$
$=\displaystyle\left(\int_{\rho=0}^{\rho=1}\rho^3e^{\rho^2}\,\mathrm d\rho\right)\left(\int_{\theta=0}^{\theta=\pi/2}\cos\theta\,\mathrm d\theta\right)\left(\int_{\varphi=0}^{\varphi=\pi/2}\sin^2\varphi\,\mathrm d\varphi\right)=\frac\pi8$
