Mathematics
1 answer:

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
