5x= one angle measure
7x= second angle measure
120°= third angle
Triangles equal 180°. Add the angles above to total 180°. Find x to find two two unknown angles.
5x + 7x + 120°= 180°
combine like values
12x + 120= 180
subtract 120 from both sides
12x= 60
divide both sides by 12
x= 5
ONE ANGLE MEASURE
5x= 5(5)= 25°
SECOND ANGLE MEASURE
7x= 7(5)= 35°
CHECK:
25° + 35° + 120°= 180°
180°= 180°
ANSWER: The measures of the two angles are 25° and 35°.
Hope this helps! :)
Answer:
x > 1
interval (1,∞)
Step-by-step explanation:
1/2(-2x - 12) > 7(3 - 4x)
-x - 6 > 21 - 28x
-x + 28x > 21 + 6
27 x > 27
x > 27 / 27
x > 1
interval (1,∞)
-x - 6 > 21 - 28x if x = 2
-2 - 6 > 21 -28(2)
-8 > 21 - 56
- 8 > - 35
Answer:
hi have a great day i dont know about this
Step-by-step explanation:
Answer:
The answer to your question is below
Step-by-step explanation:
Data
Methane: 1 carbon and 4 hydrogens
A sample 92 hydrogen atoms / carbons = ?
total atoms = ?
Process
1 : 4 :: x : 92
x = number of carbons
x = (92 x 1) / 4
x = 92 / 4
x = 23 carbons
Total atoms = hydrogen atoms + carbon atoms
= 92 + 23
= 115 atoms
