Answer:
<h2>
∠PQT = 72°</h2>
Step-by-step explanation:
According to the diagram shown, ∠OPQ = ∠OQP = 18°. If PQT is a tangent to the circle, it can be inferred that line OQ is perpendicular to line QT. Ths shows that ∠OQT = 90°.
Also from the diagram, ∠OQP + ∠PQT = ∠OQT;
∠PQT = ∠OQT - ∠OQP
Given ∠OQP = 18° and ∠OQT = 90°
∠PQT = 90°-18°
∠PQT = 72°
Answer:
(2v-1)(21v^2+17)
Step-by-step explanation:
add and subtract the second term to the expression and factor by "grouping"
answer should be:
(2v-1)(21v^2+17)
Answer:
<h2>One solution.</h2>
Step-by-step explanation:
The given question is
<em>Does the following system have One Solution, No Solution, or Infinite Solutions.
</em>
<em />
<em />
<em />
<em />
To solve this system, we just need to multiply the first equation by -1, and then sum those equations.


Then, we use this value to find the other one

As you can observe, the system of equations have a unique solution.
Therefore, the answer is one solution.
