Question

In the given figure,
if angle P =125°, then measure of angle R is ( refer to the picture above ) step by step explanation.
​

Answer 1

Note: $\[\angle P = 25^\circ \]$

Given,

$\[\angle P = 25^\circ \]$

Solution,

Know that the sum of the angles of a triangle is $\[180^\circ .\]$

Know that in a right-angled triangle one angle is $\[90^\circ .\]$

Therefore, the angle R is given as

$\[\begin{array}{l} \Rightarrow 90^\circ + 25^\circ + \angle R = 180^\circ \\ \Rightarrow \angle R = 180^\circ - \left( {90^\circ + 25^\circ } \right)\\ \Rightarrow \angle R = 180^\circ - 115^\circ \\ \Rightarrow \angle R = 65^\circ \end{array}\]$

Hence, the angle R is $\[65^\circ .\]$
