I’m this you should know that it is best to find the area of each triangle then add them together

As you see the base is 24 so you take half of 24 for the base of your triangles and you get 12

1/2 is one half

TRIANGLE A

A = 1/2( Base (times) height)
A = 1/2(12 (times) 35) = 210

The formula will be the exact same for the other triangle.

When adding the areas up you get 420 squared inches.

Therefore answering is 420 in^2

One triangle has an angle of 81 degrees and the corresponding angle of the other triangle is 2x - 5 degrees, find the value of x
Delicious77 [7]

Answer:

x=43

Step-by-step explanation:

Corresponding angles are equal. It is implied that the two angles referred to in the triangles are equal, otherwise they should not be labelled as corresponding.

Therefore, we can set both equations equal to each other:

2x-5=81^{\circ}

Add 5 to both sides:

2x=86

Divide both sides by 2:

x=\frac{86}{2}=\boxed{43}

an organic farm uses 3/7 of the land to grow potatoes and two fifths of the land to grow spinach the remaining land is used to g
melomori [17]
<span>The organic farm uses 3/7 of the land to grow potatoes
=> 2 /5 of the land to grow spinach
=> x = the fraction of the land to grow tomato plants.
The easiest wat to get the answer is convert first the fraction to decimals
=> 3/7 = 0.43
=> 2/5 = 0.4
=> x = ???
=> 0.43 + 0.4 = 0.83
=> let the whole land = 1
=> 1 – 0.83
=> 0.17, the remaining land left for tomato plants
Convert now to fraction
=> 17/100</span> (Approximately)

YOu can also use this method:
=> 3/7+ 2/5 +x = ?
Find the LCM
=> 3/7 + 2/5 = 29/ 35
=> 35/35 - 29 / 35
=> 6 / 35, the remaining land
