Answer:
Step-by-step explanation:
∠1 & ∠2 are co interior angles. co interior angles are supplementary.
∠1 + ∠2 = 180
102 + ∠2 = 180
∠2 = 180 - 102
∠2 = 78°
Answer:
9
Step-by-step explanation:
In the notation of a function f(x) = x+8, for input x=1 the output would be 9. And (1,9) would be an (x,y) pair that fits the function.
Answer:
24.03 units (nearest hundredth)
Step-by-step explanation:
The distance between B and A is: AB = AH + HB
We have been given AH, so we just need to find the measure of HB.
First, find the angle AOH using tan trig ratio:

where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
Given:
= ∠AOH- O = AH = 8
- A = OH = 19.80


∠BOA = ∠BOH + ∠AOH
⇒ ∠BOH = ∠BOA - ∠AOH
⇒ ∠BOH = 61° - 22.00069835°
= 38.99930165°
Now we can find HB by again using the tan trig ratio:
Given:
= ∠BOH = 38.99930165°- O = HB
- A = OH = 19.80
Substituting given values:



Therefore:
AB = AH + BH
⇒ AB = 8 + 16.03332427
= 24.03 units (nearest hundredth)
Answer:
t(d) = d/65
Step-by-step explanation:
To solve for t, divide by its coefficient:
d = 65t
d/65 = 65t/65 . . divide* by 65
d/65 = t . . . . . . . simplify
Then you can write it in function form if you like:
t(d) = d/65
_____
* Of course, the rules of equality say you must divide <em>both sides</em> of the equation by the same number.
