Answer:

27+18=45

Step-by-step explanation:

x+y=45

x+9=y

(x+9)+x=45

(18+9)+18=45

27+18=45

The height of a triangle is 2 less than 3 times it's base. If the area of the triangle is 48cm squares determine the base and he

Artyom0805 [142]

<h3>answer</h3>

we assume the height of the triangle is x,

so the base length will be x+4

the triangle area will be area = 1/2 ( base * height)

48 = 1/2 (x + 4) x

96 = x2 + 4x

96 + 4 = x2 + 4x + 4

100 = (x + 2)2

10 = x + 2 (for the square 100, we ignore the -10, minus is meaningless in length )

x = 8

x + 4 = 8 + 4 = 12

so the height for the triangle is 8 unit, base is 12 unit,

brainliest ♥️

If the length,l, of the yard is 18 feet longer than the width ,w, of the yard, what is the area of the yard , in square yard

Advocard [28]

Answer: The area is $w^{2}$ + 18w

Step-by-step explanation:

We could represent the length of the yard by l = w+18 and the width as w .

And to find the area we will have to multiply the length by the width.

A= w(w+18 ) multiply

A= $w^{2}$ + 18w

Answer:

Let me know if you want more explanation

Step-by-step explanation:

Alright, to solve for x we need 2 angles that are congruent or equal.

I'm going to use the two we will need later. KLN and MNL

Now to find x ^^

$2x-18=x+6\\2x-18-x=x+6-x\\x-18=6\\x-18+18=6+18\\x=24$

Now we just need to plug it into each angle. I'm going to show you them separately.

$KLN=2x-18\\KLN=2(24)-18\\KLN=48-18\\KLN=30$

$MNL=4x-6\\MNL=4(24)+6\\MNL=102$

should be right now.

2.2.4 quiz exterior and remote interior angles PLEASEEEE

Sloan [31]

Answer:

Option (A)

Step-by-step explanation:

By applying the theorem angle theorem in the given triangle,

Sum of exterior angle of a triangle is equal to the sum of opposite interior angles of the triangle.

Therefore, 130° = y° + y°

130° = 2y°

y = $\frac{130}{2}$

y = 65°

Therefore, measure of interior angles 'y' of the given triangle will be 65°.

Option (A) will be the answer.
