Answer:
case A. 
case B. 
case E. 
Step-by-step explanation:
we have

we know that

<u>Verify each case</u>
case A) 

therefore
is equivalent to 
case B) 
so
is equivalent to 
case C) 

therefore
is not equivalent to 
case D) 
so
is not equivalent to 
case E) 

therefore
is equivalent to 
case F) 
so
is not equivalent to 
2x+x=180
3x=180
X=60
And other angle is 120
Answer:
<h2>
The right option is twelve-fifths</h2>
Step-by-step explanation:
Given a right angle triangle ABC as shown in the diagram. If ∠BCA = 90°, the hypotenuse AB = 26, AC = 10 and BC = 24.
Using the SOH, CAH, TOA trigonometry identity, SInce we are to find tanA, we will use TOA. According to TOA;
Tan (A) = opp/adj
Taken BC as opposite side since it is facing angle A directly and AC as the adjacent;
tan(A) = BC/AC
tan(A) = 24/10
tan(A) = 12/5
The right option is therefore twelve-fifths
Answer:
D
Step-by-step explanation:
The Surface area of the cube will be 433.5 square feet. Then the correct option is C.
<h3>What is a surface area of a cube?</h3>
Suppose that: The side length of the considered cube is L units. Then, we get:
Surface area of that cube = 6L² square units.
Bella is wrapping a cube shape box that measures 8.5 inches along each side.
The edge length of the cube is 8.5 meters.
Then the Surface area of the cube will be
Surface area = 6 x 8.5²
Surface area = 6 x 72.25
Surface area = 433.5 square feet
The Surface area of the cube will be 433.5 square feet.
Then the correct option is C.
