Answer:
EH = 3.31
Step-by-step explanation:
We have been given a right angle triangle EKL. As KH has been given as the altitude (perpendicular) of the right angled triangle, and K is the right angle, we can say that EK is tthe base of the triangle and EH is the only side lleft, which is the hypotenuse of the triangle.
Where,
EK = Base = 3
KH = perpendicular altitude
EH = Hypotenuse
m<K = 90
m<E = 25
We know that
cosθ = Base/ Hypotenuse
cos 25 = 3/ EH
EH = 3/cos25
EH = 3.31
Perpendicular alitutude can also be calculated by using the formula for tanθ.
Answer:
x=10
Step-by-step explanation:
7x+70=16x-20
70=9x-20
9x=90
x=10
Answer:
2.82
Step-by-step explanation:
Answer:
Step-by-step explanation:
5x + 5y = 20
2x - 5y = 15
7x = 35
x = 5
5 + y = 4
y = -1
(5, -1)
A new shape with an area of 1 square unit that is not a square can be formed by combining two small triangles
<h3>How to determine the new shape?</h3>
The given parameters are:
- Area of square = 1 square unit
- Large triangles = 2
- Medium triangles = 1
- Small triangles = 4
The area of each small triangle is:
Area = 0.5 square unit
Multiply both sides by 2
2 * Area of triangle = 1 square unit
Substitute Area of square = 1 square unit
2 * Area of triangle = Area of square
This means that a new shape can be formed by combining two small triangles
