61° all triangles equal 180 so all you do is add up each of the angles then subtract it from 180

According to triangle sum property ,
Angle A + Angle B + Angle C = 180°
Therefore ,
Angle A + 34° + 65° = 180°
Angle A + 99° = 180°
Angle A = 180° - 99°
= 81°
Answer is
Angle A = 81 °

Answer:

$\huge \boxed{ \boxed{\mathbb{B)} \frac{40}{6} }}$

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

equation
PEMDAS

<h3>given:</h3>

8×⅚=z

<h3>let's solve:</h3>

$\sf multiply \: both \: sides \: by \: 6 : \\ (8 \times \frac{5}{6} ) \times 6 = z \times 6$
$\sf simplify : \\ 8 \times 5 = 6z \\ 40=6z$
$\sf divide \: both \: sides \: by \: 6 : \\ \frac{6z}{6} = \frac{40}{6} \\ z = \frac{40}{6}$
