<h3>Given</h3>
- ∠AOB = ∠COD = x² -2
- ∠BOC = 2x -10
- ∠AOD = ∠AOB + ∠BOC + ∠COD = 16x +2
<h3>Find</h3>
- x
- the measures of the angles
<h3>Solution</h3>
Substituting the given values of the angles into the given relaion, we get ...
... (x² -2) + (2x -10) + (x² -2) = 16x +2
... 2x^2 -14x -16 = 0 . . . . . subtract the right side (16x+2)
... 2(x +1)(x -8) = 0 . . . . . . .factor
Values of x that satisfy this equation are ...
... x = -1, x = 8
The value x = -1 does not give rise to positive angle values.
For x = 8, the angles are ...
... ∠AOB = ∠COD = 8²-2 = 62
... ∠BOC = 2·8 -10 = 6
... ∠AOD = 16·8 +2 = 130 . . . . = 62 +6 +62
The answer to the question not asked is ...
... x = 8; ∠AOB = ∠COD = 62; ∠BOC = 6; ∠AOD = 130
Answer:
Step-by-step explanation:
I think the answer choices were supposed to be:
Pythagorean Theorem: a²+b²=c²
5²+b²=8²
25+b²=64
<em>Subtract 25 from both sides</em>
b²=39
<em>Square root both sides</em>
b=
Our answer is
To find the inverse of a function, we swap x and y then solve for y
So with this, we take y = 3x + 4 and make it x = 3y + 4. Now we solve for y
x = 3y + 4
Subtract 4 from both sides
x - 4 = 3y
Divide both sides by 3
<span>She could round this number
may it be in the tens and hundreds place. When rounding off a number, one
should consider the place of the digit he or she would like to round it off to.
One should consider what number is placed at the right of the rounding number.
If the number is below 5, then that digit should remain and the rest of the
digits to the right should be turned to 0s. </span>
