Answer:

<u>13.2 centimeters</u>

Step-by-step explanation:

<u>Finding the missing side</u>

  • (?)² + (9)² = (16)²
  • ?² + 81 = 256
  • ?² = 175
  • ? = √175
  • ? = <u>13.2 centimeters</u>

Hey mate ,

In this question we have given the length of hypotenuse and base of a right angle triangle and asked us to find the perpendicular length

  • Hypotenuse = 16cm
  • base = 9cm

<u>According</u><u> to</u><u> </u><u>Pythagoras</u><u> theorem</u><u> </u><u>,</u><u> </u>

Hypotenuse² = Perpendicular²+base²

16cm² = (P)² + 9cm²

256 - 81 cm = P²

√175 cm = P

<u>Perpendicular</u><u> </u><u>=</u><u> </u><u>1</u><u>3</u><u>.</u><u>2</u><u>2</u><u> </u><u>cm</u>

The missing number is 20

<h3>How to determine the number</h3>

We can see that the values at the top must be made equal to that at the bottom

For the top, we have

30 + 11 = 41

For the bottom, we should have:

21 + x = 41

Now, let's solve for 'x' to determine the missing figure;

21 + x = 41

collect like terms

x = 41 - 21

x = 20

Thus, the missing number is 20

Use the functions h(x) = 2x − 5 and t(x) = 6x + 4 to complete the function operations listed below.
Anika [276]
For this case we have the following functions:
 h (x) = 2x - 5
 t (x) = 6x + 4

 Part A: (h + t) (x)
 (h + t) (x) = h (x) + t (x)
 (h + t) (x) = (2x - 5) + (6x + 4)
 (h + t) (x) = 8x - 1

 Part B: (h ⋅ t) (x)
 (h ⋅ t) (x) = h (x) * t (x)
 (h ⋅ t) (x) = (2x - 5) * (6x + 4)
 (h ⋅ t) (x) = 12x ^ 2 + 8x - 30x - 20
 (h ⋅ t) (x) = 12x ^ 2 - 22x - 20

 Part C: h [t (x)]
 h [t (x)] = 2 (6x + 4) - 5
 h [t (x)] = 12x + 8 - 5
 h [t (x)] = 12x + 3

Find the area of the triangle, also am I correct???
Ierofanga [76]

Answer:

The area of the triangle is 10.92 cm².

Step-by-step explanation:

The formula for the area of a triangle is

A=\frac{1}{2}bh

where b is the length of the base and h is the height. We know that b = 2.8 and h = 7.8, so you would substitute into the formula:

A=\frac{1}{2}(2.8)(7.8)=10.92 cm²
