Since PQ is tangent to the circle, angle PQO is 90°.
Since the sum of angles of any triangle must be 180° we can say:
180-90-12=x thus:
x=78°
Answer:
<h2>f(n) = 0.15n + 0.35</h2>
Step-by-step explanation:
The sequence of the problem above is an arithmetic sequence
For an nth term in an arithmetic sequence
F(n) = a + ( n - 1)d
where a is the first term
n is the number of terms
d is the common difference
To find the equation first find the common difference
0.65 - 0.5 = 0.15 or 0.80 - 0.65 = 0.15
The first term is 0.5
Substitute the values into the above formula
That's
f(n) = 0.5 + (n - 1)0.15
f(n) = 0.5 + 0.15n - 0.15
The final answer is
<h3>f(n) = 0.15n + 0.35</h3>

Answer:
38
Step-by-step explanation:
Step-by-step explanation:
Each coloured figure have 32 squares and there are a total of 6 coloured figures (the orange parts between the 2 squares are a part of the same figure)
Since 100 squares = 1 whole, 32 squares = 0.32.
Therefore we have 6 * 0.32 = 1.92. (B)
