Question

Please help me with my Geometry homework!! I only need 18 and 20

Answer 1

Number 20 is 104

Explanation:

A triangle with interior angles will always equal 180. To sum this down to simple addition and subtraction, we can add 38 plus 38.

Our equation is:

x + 38 + 38 = 180

Like I said, we add 38 by 38.

38 + 38 = 76

Then we take our sum and subtract it by 180 to get x

180 - 76 = 104

x = 104

Hope this helps! :3

Answer 2

17) Angle 1 measures 180° - (75° + 35°) = 180° - 110° = 70°.

18) Angle 2 measures 110°.

19) Angle 3 measures 180° - (70° + 28°) = 180° - 98° = 82°.

20) x = 180° - 76° = 104°
