Which expression finds the length of side b of this right triangle. PLEASE HELP. I’LL GIVE BRAINIEST

The answer is b = √(c² - a²).

Step-by-step explanation:

For right angle triangle, you can apply Pythagoras Theorem where c² = a² + b² .

Answer:

Step-by-Step Explanation:

In the given right-angled triangle, the largest angle is 90°. And side c is opposite to it, hence c is the hypotenuse.

Then, a and b are the leg sides of the triangle i.e. base and perpendicular. Then, By using Pythagoras theoram:

Now shifting a² by subtracting from both sides,

We need b, square rooting both sides

That is Option B. And we are done! :D

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
