Answer: 45.. i think.
Step-by-step explanation: I couldn't really get the measurements from this photo so here is what I got. I used the formula A=a+b over 2 times h. I used 7=a, b=11,h=5. I added 7 and 11 to get 18, then divide that by 2, which equals 9. Then 9 times 5 = 45. I hope this somewhat helps.
Answer:
Its the one at the bottom on the left
Step-by-step explanation:
It is that one because one its a polygon and has angles and is congruent
Answer:
The answer to your question is log₁₀ x + b = a
Step-by-step explanation:
General formula
Logarithmic function Exponential function
log ₐ b = c 
a = antilogaritm c = exponent
b = base b = base
c = logaritm a = power
In your problem
10 = base
a = exponent
x + b = power
Exponential function log₁₀ x + b = a
3x5=$15
15+10=$25 total to spend
He spends 12.75+8.5= $21.25
25-21.25=$3.75 left
Answer:
See explanation
Step-by-step explanation:
The given trigonometric equation is
.
We take the inverse cosine of both sides to get:

to the nearest degree
None of the options satisfies the given equation.
But if the question is actually;

Then;
