Answer:
90 degrees
Step-by-step explanation:
A circle circumscribed over a right triangle is the same as a circle circumscribed over a rectangle built from the extension of the right triangle.
That tells us that the hypotenuse is the diameter of the circle in that case.
Here, we can see a triangle that has the hypotenuse as the diameter of the circumscribed circle. We can infer that the triangle is a right triangle.
Answer:
∠BAC = 105°
Step-by-step explanation:
2(5x) = 9x+21
10x = 9x+21
reduce:
x = 21
∠BAC = 5x = 105°

Answer:
$125 per week
Step-by-step explanation:
Andrew earns $6.25 per hour. If he works for 4 hours, solution will be:
$6.25 × 4 = $25 per day.
If Andrew works 5 days per week, then he earns
$25 × 5 = $125 per week.
Therefore by estimate, Andrew earns $125 per week.
Answer:
Step-by-step explanation:
f(x)=2-x
x=2-y
add y both sides, then subtract x from both sides
y=2-x or f(x)=2-x same thing
