zysi [14]

Answer:

A.

Step-by-step explanation:

12.5/10=1.25.

12.5/8=1.56

12.5/12=1.04

12.5/6=2.08

it's important to know what 1/2 is, 1/3 is, 1/4 is and 1/5 it's also important to know things like 2/2, 2/3, 3/3, 2/4, 3/4, 4/4, 2/5, 3/5, 4/5, and 5/5. You don't need this until 8th grade though. But get on it if you can. Ask your parents or teacher.

Two of the exterior angles of a triangle are $158^\circ$ and $99^\circ.$ Find the third exterior angle, in degrees.
Lisa [10]

Answer:

The third exterior angle is 103^o

Step-by-step explanation:

Given

\theta = 158^o

\alpha = 99^o

Required

The third exterior angle (\beta)

The exterior angles of a triangle add up to 360 degrees.

So:

\theta + \alpha + \beta = 360^o

Make \beta the subject

\beta = 360^o - (\theta + \alpha)

Substitute known values

\beta = 360^o - (158^o + 99^o)

\beta = 103^o
