We can automatically rule out both Right and Equilateral Triangles, this is because there is no 90 degree angle (Needed for a right triangle) and all three angles are not equal (needed for an equilateral triangle).
Looking a little deeper, we know that an isosceles triangle has two congruent (or same) angles. Meaning we can rule this one out as well.
This leaves option A) Scalene Triangle
And to check, we think about a scalene triangle, and we know it's a triangle that has 3 unequal sides, meaning that this could qualify!
Volume = area of base * height = 12 1/6 * 2 3/4 = 73/6 * 11/4 = 803/24
= 33 11/24 cubic feet
We know that
cos²(theta)=0.21
sin²(theta)+cos²<span>(theta)=1
</span>sin²(theta)=1-cos²(theta)------> sin²(theta)=1-(0.21)-----> 0.79
sin(theta)=√0.79
sin(theta)=0.89
the answer is
the value of sin(theta) is 0.89
Answer:
a = v / x ^ 2 - b / x - c / x ^ 2 :))))))
$3.50 I believe because the cost of ONE cup of coffee and 3 donuts is $3.70. And 2 cups and 2 donuts are 10 cents more. So ONE cup and ONE donut are $3.50 I beleve
