Question

Can someone pls help me

Answer 1

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}}}`

Answer 2

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
