Answer:
Step-by-step explanation:
Note that the entire segment RT is the combined lengths of RS and ST. So:
We know that RT is 108, RS is (9y+5), and ST is (3y+7). Substitute:
On the right, combine like terms:
Add:
Subtract 12 from both sides. The right cancels:
Divide both sides by 12:
So, the value of y is 8.
To find RS and ST, substitute 8 for y. So:
Substitute 8 for y:
Multiply:
Add:
Do the same for ST:
Substitute 8 for y:
Multiply:
Add:
Answer:
Step-by-step explanation:
The measure of an angle is the coterminal angle with a 45A°+360A° and can be determined by using the measurement of coterminal angles.
<h2>We have to determine</h2>Which expression finds the measure of an angle that is coterminal with a 45° angle?
<h3>According to the question,</h3>Coterminal angles are those angles that share the terminal side of an angle occupying the standard position.
The standard position means that one side of the angle is fixed along the positive x-axis, and the vertex is located at the origin.
<h3>A coterminal with 45° is 45°+k°360° with k as an integer.</h3>Then,
The coterminal angle with 45°,
When k = 0
Then,
When k = 1
Then,
When k = -1
Then,
Hence, The measure of an angle that is coterminal with a 45A°+360A°.
