What is the measurement of angle POR

IgorLugansk [536]

Let us observe the given figure,

When two lines intersect each other, the angles opposite to each other are Vertically Opposite Angles. Vertically opposite angles are always equal in measure.

As, we can observe that the given lines intersect each other, and they form vertically opposite angles as $\angle POR , \angle SOQ$ and $\angle POS , \angle ROQ$

Therefore, $\angle POR = \angle SOQ$

Substituting the given measures of the angles, we get

$91-x^\circ = x+ 7^\circ$

$91-7 = x + x$

$84 = 2x$

$x = \frac{84}{2}$

So, x = $42^\circ$

Since, the measure of angle POR = $(91-x)^\circ$

= $(91-42)^\circ$

= $49^\circ$

Therefore, the measure of angle POR is 49 degrees.

lesya692 [45]

Answer:

Step-by-step explanation:

If I understand the question right, G(t) = -((t-1)^2) + 5 and we want to solve for the average rate of change over the interval −4 ≤ t ≤ 5.

A function for the rate of change of G(t) is given by G'(t).

G'(t) = d/dt(-((t-1)^2) + 5). We solve this by using the chain rule.

d/dt(-((t-1)^2) + 5) = d/dt(-((t-1)^2)) + d/dt(5) = -2(t-1)*d/dt(t-`1) + 0 = (-2t + 2)*1 = -2t + 2

G'(t) = -2t + 2

This is a linear equation, and the average value of a linear equation f(x) over a range can be found by (f(min) + f(max))/2.

So the average value of G'(t) over −4 ≤ t ≤ 5 is given by ((-2(-4) + 2) + (-2(5) + 2))/2 = ((8 + 2) + (-10 + 2))/2 = (10 - 8)/2 = 2/2 = 1

xenn [34]

The exponential graph is shown below.

The initial value when the time is zero is 70000. An initial value is normally shown as the point where the graph crosses the y-axis.

If the initial value was to be 50000, the curve would have crossed the y-axis at 50000
