Answer:

x=17°

Step-by-step explanation:

Because the diagonal lines are marked with arrows, we know that they are parallel. The two angles that are marked with measures are same-side interior angles. Same-side interior angles of parallel lines are supplementary, meaning that the sum of their measures is 180°.

Now, with all of this information, we can set up the following equation and solve for x:

115+4x-3=180

112+4x=180 (Simplify LHS by combining like terms)

112+4x-112=180-112 (Subtract 112 from both sides of the equation to isolate x)

4x=68 (Simplify)

\frac{4x}{4}=\frac{68}{4} (Divide both sides of the equation by 4 to get rid of x's coefficient)

x=17° (Simplify)

Hope this helps!

Given:

Two similar rectangles.

To find:

The area of the larger rectangle.

Solution:

Let x be the other side of the larger rectangle.

Corresponding sides of similar figures are always congruent.

\dfrac{x}{1}=\dfrac{4}{2}

x=2

The other side of larger rectangle is 2 cm.

We know that, area of rectangle is

Area=Length\times Width

So, area of the larger rectangle is

Area=4\times 2

Area=8

Therefore, the area of the larger rectangle is 8 sq. cm.

Help me with this please.

Answer:

JL = 78

Step-by-step explanation:

MN is a midsegment. Based on the midsegment theorem,

MN = ½(JL)

MN = 5x - 16

JL = 4x + 34

Plug in the value

5x - 16 = ½(4x + 34)

5x - 16 = ½*4x + ½*34

5x - 16 = 2x + 17

Collect like terms

5x - 2x = 16 + 17

3x = 33

Divide both sides by 3

x = 11

✔️JL = 4x + 34

Plug in the value of x

JL = 4(11) + 34

JL = 44 + 34

JL = 78
