Question

can anyone help me ----------------

Answer 1

Answer:

for A - total sum angle is 180

so 180-113= 67

B = 46 vertically opposite angles

C 180-(67+46)

180-(. 113)

c = 67

or angle a = c

alternate Interior angles

Answer 2

NAMASTE, ◉‿◉

Sol.

Here,

A = 113°

But,

Angle CAB = 180° - 113° ( linear pair ) = 67°

Also,

Angle ACB = 67° ( Alternate )

As,

Both angles ACB and CAB are equal,

So,

Triangle ABC is an Isosceles ∆ .
