Question

Can someone pls help me

Answer 1

Answer:

Step-by-step explanation:

∠A + ∠B + ∠C = 180      {Angle sum property of triangle}

∠A + 65 + 55 = 180

       ∠A + 120 = 180

                ∠A = 180 - 120

               ∠A = 60

If two triangles are similar, then the corresponding angles of two triangles are congruent.

z = ∠A

z = 60

Answer 2

Solution -:

In ∆ ABC,

$\angle$ A + $\angle$ B + $\angle$ C = 180° .... (Angle sum property of a triangle)

Here, we have:

• $\angle$ B = 65°

• $\angle$ C = 55°

Substituting values,

$\dashrightarrow\sf{\angle A + 65 + 55 = 180} \\ \\ \dashrightarrow\sf{\angle A + 120 = 180} \\ \\ \dashrightarrow\sf{\angle A = 180 - 120} \\ \\ \dashrightarrow{\boxed{\sf{\gray \angle A = 60 \: \bigstar}}}$

As we know that,

★ If two triangles are similar, then the corresponding sides of two triangles are congruent.

$\longrightarrow\tt{z= \angle A } \\ \\ \longrightarrow{\boxed{\tt{\gray Z = 60 \: \bigstar}}}$
