Question

two angles <A and < B are vertically opposite angles if m<A=70° then m<B=
1) 20°
2) 30°
3) 110°
4) 70°​

Answer 1

Answer:

4) 70 , as it is vertically opposite angle so the answer is 70.

( vertically opposite angles are equal)

Step-by-step explanation:

do not depend on the answer

as it is not sure to be correct.

Answer 2

Given:

two angles $\[\angle A\]$and $\[\angle B\]$ are vertically opposite angles if m$\[\angle A\]$=70° then m$\[\angle B\]$=

Solution:

Know that the measures of the opposite angle are same.

Therefore,

$\[\begin{array}{l} \Rightarrow \angle B = \angle A\\ \Rightarrow \angle B = 70^\circ \end{array}\]$

Hence, the measure of $\[\angle B\]$ is $\[70^\circ \]$.
