Answer:
180
Step-by-step explanation:
V=1/3Bh=1/3*1*2=2/3
20*6=120
120 divided by 2/3 is 180
Answer:
infinitely many solutions
Step-by-step explanation:
solve by substitution:
solve equation 1 for y: - y = 7 - 4x; divide by -1 to simplify into y = -7 + 4x
Substitute - 7 + 4x into the second equation to obtain:
3(-7 + 4x) - 12x = -21, which yields:
-21 + 12x - 12x = -21, which simplifies 0 = 0
a result of 0 = 0 means infinite solutions such as:
(2,1), (3, 5), (4, 9), (5, 13), (6, 17)....
Since both angles are equal to each set the equations equal to each other.
X+35=3x+1
1. Subtract 1 from both sides. Gives you = x+34=3x
2. Subtract 1x from both sides. Gives you 34=2x
3. Divide 2 on both sides, gives you 17=x.
4. Answer is 17=x.
Answer:
<em>Answer: SAS</em>
Step-by-step explanation:
We must prove that triangles ABC and EDC are congruent.
Since BD bisects AE, then AC is congruent with CE.
Since AE bisects BD, then BC is congruent with CD
Angle C is 90° in the triangle EDC and is also 90° in triangle BCA because they are vertical angles.
Being two sides and the included angle congruent, then both triangles are similar by the SAS theorem.
