Answer: 50°

Step-by-step explanation:

First, we can see that this is an isosceles triangle! That means the two angles at the bottom are the same.

A triangle's angles all equal 180 when added together, so knowing this, lets work backwards

180 - 80 = 100

Now, the two angles at the bottom are the same, so lets just divide 100 by 2, and our answer is 50!

Hope this helps :)

Answer:

x = 50°

Step-by-step explanation:

x = (180 - 80) ÷ 2

= 100 ÷ 2

= 50°

The diagram below shows an Isosceles triangle. Label the base angles and the vertex

Dmitry [639]

The base angles of an isosceles triangle are equal

The base angles are 15 degrees, while the vertex angle is 150 degrees

The base angles are given as:

Base = (6a- 3) and (a + 12)

So, we have:

$\mathbf{6a -3 =a + 12}$

Collect like terms

$\mathbf{6a -a =3 + 12}$

$\mathbf{5a = 15}$

Divide both sides by 5

$\mathbf{a = 3}$

Substitute 3 for a in Base = (6a- 3),

$\mathbf{Base = 6 \times 3 - 3}$

$\mathbf{Base = 18 - 3}\\$

$\mathbf{Base = 15}$

So, the base angle is 15 degrees.

The vertex angle is calculated using:

$\mathbf{Vertex=180 -2 \times Base}$

So, we have:

$\mathbf{Vertex=180 -2 \times 15}$

$\mathbf{Vertex=150 }$

Hence, the vertex angle is 150 degrees
