Answer:
B) ∠B ≅ ∠K
Step-by-step explanation:
The Angle-Angle-Side Postulate (AAS) states that if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the two triangles are congruent.
Given that ∠A ≅ ∠J and AC ≅ JL, then we need that ∠B ≅ ∠K to satisfy postulate AAS (the two angles are ∠A and ∠B in one triangle and ∠K and ∠J in the other one, and the non-included side is AC in one triangle and JL in the other one).
Answer:
Area of rectangle = 80
Area of Half Circle 8π
Step-by-step explanation:
The area of the rectangle is width x length, so:
Area of Rectangle: 8x10=80 ft^2
Since we know that this is a rectangle, opposite sides are equal, hence the half circle's diamiter being 8 as well.
The area of a circle is πr^2 and half-circle being πr^2/2, so with radius 4 (d/2= 8/2=4)
Area of half circle= π(4)^2= 16π/2= 8π
Answer:
Solve
Step-by-step explanation:
To find the surface area of a triangular prism, use the formula Surface Area = L + 2B, where L is the lateral area and B is the area of the base. Find the lateral area by calculating the perimeter of the base and multiply it by the height of the prism.
Answer:
x = -9/4
Step-by-step explanation:
x/3 - 2 = - 11/4
Add 2 to each side
x/3 - 2+2 = - 11/4+2
Get a common denominator on the right
x/3 = -11/4 + 8/4
x/3 = -3/4
Multiply each side by 3
x/3*3 = -3/4 *3
x = -9/4
