Answer:
a = 45°
Step-by-step explanation:
In triangle PSR
PS = RS (Given)
angle SPR = angle SRP (isosceles triangle property)
Let angles SPR and SRP be x
Therefore, 90° + x + x = 180° (angle property)
=> 90° + 2x = 180°
=> 2x = 180° - 90° = 90°
=> 2x = 90°
=> x = 90° ÷ 2 = 45°
=> x = 45°

Answer: 2 1/4 in.
Step-by-step explanation:
make the denominaters the same (4) and then subtract 20 3/4 - 18 2/4 which is 2 1/4.
hope this helps let me know if you need anything else! :')
We first solve the angle from the given sinθ=3/5. Using a calculator in degrees mode, theta is equal to 36.87 degrees. Hence 2 theta is equal to 73.74 degrees. The value of cosine 73.74 degrees is equal to 7/25. This is the final answer.
A bill for repairing the breaks on the Johnsons car was $125.25. If 20% of the bill was for parts and the rest for labor, how much were the Johnsons charged for labor?
Answer:
The function concerning the evolution of the value of the first car is exponential and the one concerrning the value of the second car is linear
Step-by-step explanation:
1st car's drop in value ( not considering the second hand type of drop):
1.4500$
2.4050$
3.3645$
2nd car's value is dropping 3000$ every year so the function is f(n)=45000-3000n, n- number of years
