Question

Please help ill give brainiest answer!

Answer 1

1. First of all, this is a isosceles triangle, meaning measurement I=58°, which makes it way easier to find T.

$58 + 58 + x = 180$

$116 + x = 180$

$x = 64$

1. m{t}°=64 m{I}°=58

2. This one is easy because algebra is the key.

$100 - x + 30 + 4x + 7x = 180$

Add like-terms.

$130 +10x = 180$

$10x = 50$

$\frac{50}{10} = x = 5$

x=5

The only thing that confuses me is the y. Is it 7xy, y as a side, or what? Feel free to reply
