Answer:
121°
Step-by-step explanation:
The angle with measure x is an exterior angle of the triangle.
The angles measuring 90° and 31° are the remote interior angles to the exterior angle.
<em>Theorem:</em>
<em>In a triangle, the measure of an exterior angle equals the sum of the measures of its remote interior angles.</em>
x = 31 + 90
x = 121°
Answer: 40%
Step-by-step explanation:
first you symplify your fraction:
12/30 = 2/5
then divide your numerator from your denominator:
2÷5 =0.4
then you convert your decimal into a percentage:
0.4×100=40%

Angles DBA and CBE are congruent because they form a vertical pair.
The interior angles of any triangle sum to 180º in measure, so it follows that angles A and E must be congruent.
Answer:
E=5(m+c)
Step-by-step explanation:
Since Bryan earns $5 for every lawn mowed, the equation right now is 5m. We have to add the $5 for the cars washed, 5c.
- 5m+5c
- That can be factored, 5(m+c)
