Answer: 5
Step-by-step explanation:
By the inscribed angle theorem.

Answer:
sin A = 3/5
cos A = 4/5
tan A = 3/4
Step-by-step explanation:
Using the trigonometric ratios;
SOH CAH TOA
Sin A = opposite/hypotenuse
cos A = adjacent/hypotenuse
tan A = opposite / adjacent
From the diagram given;
opposite = 3 adjacent =4
We can find the value of the hypotenuse by using the Pythagoras theorem
opposite² + adjacent² = hypotenuse²
3² + 4² =hypotenuse²
9 + 16 =hypotenuse²
25 = hypotenuse²
take the square root of both-side
√25 = √hypotenuse²
5 = hypotenuse
hypotenuse = 5
sin A = opposite / hypotenuse
sin A = 3/5
cos A = adjacent/hypotenuse
cos A = 4/5
Tan A = opposite /adjacent
tan A = 3/4
Simply divide the minutes by laps.
38 / 8 = 4.75
Hannah runs 1 lap in 4.75, or 4 3/4 minutes.
Answer:
Let us consider the expression:
(1)
Now, the quotient of power rules says that the numbers that have same base can be find by subtracting if powers are with same sign
And adding if powers are with opposite sign.
We will solve equation (1) by this quotient of power rule.
So, it can be rewritten as:

.
