Help please Question is in the picture

360 degrees in total.

Step-by-step explanation:

We are given that the m∠1 is 145 degrees, and because ∠1 and ∠2 form a straight line we can tell that 180-145 = 35.

So now here's what we know:

m∠1 = 145

m∠2 = 35

After that, we need to look at ∠5 and ∠6.

One thing we can notice right away is that ∠5 and ∠6 should measure the same as ∠1 and ∠2 (respectively) because they are corresponding angles.

Now we will add them all together to find the sum of all four angles.

m∠1 = 145 + m∠2 = 35 = 180

m∠5= 145 + m∠6 = 35 = 180

180 + 180 = 360

good luck!

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
