0.66 value of the correlation coefficient r of the data set
Answer:
Step-by-step explanation:
Answer:
sqrt (98)
Step-by-step explanation:
The two 45 degree angles result in equal length legs in this right triangle ..
use pythagorean theorem
7^2 + 7^2 = p^2
sqrt (98) = p
Applying the tangent theorem and trigonometry ratio, the measure of angle A is: 19.5°.
<h3>What is the Tangent Theorem?</h3>
The tangent theorem states that if a line is tangent to a circle, the point at which the radius is drawn to the point of tangency is a right angle.
Thus, consider triangle AKO as a right triangle.
Therefore,
- angle A = reference angle
- Ok = 5 (opposite)
- AO = 15 (hypotenuse)
Using the trigonometry ratio, SOH, we have:
sin A = opp/hyp
sin A = 5/15
sin A = 0.3333
A = 19.5°
Therefore, applying the tangent theorem and trigonometry ratio, the measure of angle A is: 19.5°.
