ANSWER

Each triangle:40 cm²

Kite : 80cm²

EXPLANATION

The area of a triangle is

\frac{1}{2}bh

The height of the triangle is

h = \frac{1}{2} (10)=5cm

and the base is 16 cm.

The area of each triangle is

= \frac{1}{2}(16)(5) = 40 {cm}^{2}

2. The total area of the kite is 2 times the area of one triangle.

= 2 \times 40 = 80 {cm}^{2}

Answer:the answer is 8

Step-by-step explanation:

because they split up the triangle which makes the height a diffrent number so u divide by 2, 16 divided by 2 = 8.

there are 120 seats in the balcony of theatre .if this 1/5 of the total seats, what's the total number of seats in the theater​
natka813 [3]

Answer:

600 seats

Step-by-step explanation:

We know there is 120 seats on a balcony and that is   \frac{1}{5}   of the total seats, we want to find the total number of seats so,

120 seats    =      \frac{1}{5}

We know that a whole fraction sums to 1 so for example   \frac{1}{5} +\frac{4}{5} =\frac{5}{5} =1

120 seats    =      \frac{1}{5}

Multiply  both sides to make it a whole fraction

600 seats =     \frac{5}{5} =1

So if there is 120 seats and that number is only    \frac{1}{5}    of the total number of seats then the total number of seats is 600

What is the surface area of the triangular prism?<br><br><br> ​
Sergeu [11.5K]

Good morning ☕️

Answer:

<h2>168 ft²</h2>

Step-by-step explanation:

the surface area of the triangular prism =

2×(the base’s area) + the lateral area

the base’s area =

\frac{6*4}{2} =\frac{24}{2} =12

the lateral area =

9×(6 + 5 + 5) = 9×16 = 9×16 = 144

finally,

the surface area of the triangular prism = 24 + 144 = 168

How do I do this?<br> Im stuck on what to do
Nastasia [14]
CD and DE are equal distance so their equations are equal:
2x+7 = 4(x-3)
2x+7 = 4x-12
Subtract 2x from both sides
7 = 2x-12
Add 12 to both sides
19 = 2x
9.5 = x
Now that u have x just plug it into the equation for DE
4(9.5-3)
38-12
26 is the answer
