1) These angles are actually equal so set the equation to…
58=5x-2
60=5x
X=12
2) These angles are also equal to each other
16x+22=134
16x=112
X=7
3) These angles are equal too
7x-1=125
7x=126
X=18
4) These angles are supplementary so they add to 180 degrees
9x+2+133=180
9x+135=180
9x=45
X=5
5) These angles are equal as well
8x-77=3x+38
5x-77=38
5x=115
X=23
6) These angles are also equal
11x-47=6x-2
5x-47=-2
5x=45
X=9
7) these also sum to 180
13x-21+5x+75=180
18x+54=180
18x=126
X=7
8) These angles add to 180 as well
9x-33+5x+3=180
14x-30=180
14x=210
X=15
In conclusion, just know how to solve simple one variable equation and know which angles are congruent and supplementary and this will be easy.
Answer:
C. 3h - 6
Step-by-step explanation:
Answer:
No solution
Step-by-step explanation:
Rearrange into quadratic form: 3x² + 0x - 3 = 0
Quadratic formula: when <em>ax² + bx + c = 0: x = (-b ± √(b² - 4ac))/2a</em>
Plug in: x = 0 ± √(0 - 4*3*3))/2a
From this, we can conclude that this equation has no solution, as <em>0 - 4*3*3 will definitely be negative</em>, and <em>a negative number can not be square rooted</em>.
Rational because you get a whole number
Multiply the exponents
3 * -2 = -6
It would be 2^-6
Format: a^-b = 1/a^b
1/2^6 = 1/64
The solution is 1/64
