yan [13]

Answer:

option 5

Step-by-step explanation:

we have diameter=75 feet

we need to find the radius

radius=diameter/2

so we write

radius=75 feet/2

finally

we have

radius=37.5 feet

Use the image to match the arc/angle measure.

IrinaK [193]

Answer:

The following measurements are:

$m\angle{STR}=23^\circ$ (Option #4)

$m{QT}=142^\circ$ (Option #7)

$mST=134^\circ$ (Option #5)

$mRQ=38^\circ$ (Option #2)

Step-by-step explanation:

To begin, we can find the measure of $\angle{STR}$ by applying the inscribed angle theorem: an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.

Since the intercepted arc (RS) is 46 degrees, we have:

$46=2\theta\\23=\theta$

Next, we can find the measure of arc QT using the same theorem. So,

$QT=2(71)\\QT=142$

Notice that the chord RT is actually a diameter. From the theorem about the inscribed angle including a diameter, we know that the intercepted arc will have a measure of $180^\circ$ . Since the arc ST is part of the arc RST, and we know RS is $46^\circ$ , we can set up and solve this equation:
