Question

how can you find ( mangle nvt )? ( 20^{circ}+20^{circ}=40^{circ} ) ( 90^{circ}-20^{circ}=70^{circ} ) ( 90^{circ}+20^{circ}=110^{circ} ) ( 90^{circ}+90^{circ}=180^{circ} )

Explanation:

Step1: Analyze the diagram

From the diagram, we know that \(\angle NVE\) is a right angle (\(90^{\circ}\)) and \(\angle EVT = 20^{\circ}\). To find \(m\angle NVT\), we need to add the measure of \(\angle NVE\) and \(\angle EVT\).

Step2: Calculate the measure

The measure of \(\angle NVE\) is \(90^{\circ}\) and the measure of \(\angle EVT\) is \(20^{\circ}\). So, \(m\angle NVT=90^{\circ} + 20^{\circ}\).
Calculating \(90^{\circ}+20^{\circ}\), we get \(110^{\circ}\).

Answer:

\(90^{\circ}+ 20^{\circ}=110^{\circ}\) (the corresponding option is the one with \(90^{\circ}+20^{\circ}=110^{\circ}\))
