Answer:
140°
Step-by-step explanation:
The value of supplement is 40 and X. We know that the sum of the sumplementary angles is 180. Therefore ,
=> x + 40° = 180°
=> x = 180° - 40°
=> x = 140°
<h3>
<u>Hence </u><u>the</u><u> </u><u>value </u><u>of </u><u>x </u><u>is </u><u>1</u><u>4</u><u>0</u><u>°</u><u> </u><u>.</u></h3>
Answer:
cos13=0.97 and sin0=0
Step-by-step explanation:
cos(13)
put in calculator and get 0.97
and do the same for sin(0).
sin(0)
0.

Answer:
C) c || d by converse of corresponding angles
Step-by-step explanation:
Only corresponding angles where transversal b crosses lines c and d are shown. All answer choices involving a||b or interior angles can be eliminated from consideration.
The "corresponding angle" theorem tells you corresponding angles are congruent if the lines are parallel.
The converse of that theorem tells you the lines are parallel if the corresponding angles are congruent. Here, the angles are shown congruent, so the "converse" theorem applies.
Represent 'a number' by x
7 times x equals 9 more than 4 times x
7 times x=9+4 times x
7x=9+4x
subtract 4x from both sides
3x=9
divide 3
x=3
the number is 3
