Answer:
y = 11.54°
Step-by-step explanation:
Reference angle = y°
Opposite side length = 4
Hypotenuse = 20
Apply trigonometric function SOH:
y = 11.536959° ≈ 11.54° (nearest hundredth)
Answer:
= 4·
Step-by-step explanation:
From the midpoint theorem, which states that the line that a line drawn such that it joins the midpoints of two sides of a triangle, is parallel to the third side of the triangle and is equal to half the length of the third side
Therefore, the lengths of the sides of ΔDEF, drawn by joining the midpoints of ΔABC is equal to half the length of and parallel to the corresponding side of ΔABC
We therefore, have that the corresponding sides of ΔABC and ΔDEF have a common ratio and a pair of sides in each triangle form same angles, therefore;
ΔDEF is similar to ΔABC by Side, Side, Side SSS similarity.
The length of the perimeter of ΔABC, = 2 × The length of the perimeter of triangle ΔEDC,
= 2 ×
∴ ≠ 4 ×
The statement which is incorrect is therefore;
= 4 ×

Answer:
The height of the given rectangular prism is 5cm.
Step-by-step explanation:
Given that the volume of the rectangular prism is
And length is and width is
That is V=5cm^3[/tex] , and
We have the volume of the rectangular prism V=lwh cubic centimeter
Substituting the values in above formula
Rewritting as below
Therefore the height is 5cm
