Because of the Vertical Angles theorem, we know that the two expressions are equal.
6x - 35 = 4x + 11
Add 35 to both sides: 6x = 4x + 46
Subtract 4x from both sides: 2x = 46
Divide by 2 on both sides: x = 23
Now, insert x into one of the equations: 6(23) - 35
138 + 35
103
103 + K = 180
Subtract 103 from both sides: K = 77
K = 77
Answer:
A) 50°, 65°, 65°
B) 45°, 50°, 85°
C) 20°, 60°, 100°
Step-by-step explanation:
To see if the angles can be used to construct triangles, you have to check if the degrees add up to 180 (Since the degrees in a triangle always have to add up to 180 degrees).
<u>A) 50° + 65° + 65° = 180° (Good!)</u>
<u>B) 45° + 50° + 85° = 180° (Good!)</u>
<u>C) 20° + 60° + 100° = 180° (Good!)</u>
<em>D) 30° + 60° + 70° = 160° (Bad!)</em>
<em>E) 20° + 45° + 120° = 185° (Bad!)</em>
Answer:
0.8
Step-by-step explanation:
3 1/2 = 3.5.... 4 3/8 = 4.375
so 3.5 Divided by 4.375 is 0.8
Answer:
50%
Step-by-step explanation:
There are 8 professors. 4 of them are younger than 47 (not equal to 47, YOUNGER)
1. 42
2. 34
3. 44
4. 36
To find percentage we have to do 4/8 x 100
this equals to 50%
