Answer:

x=21

<1=120

Step-by-step explanation:

So to find x set up an equation like this:

(5x+15)+(3x-3)=180

since the bottom and top lines are congruent they are 'interior angles on the same side of a transversal' which are always supplementary, so that's where 180 comes from.

calculate the equation and you'll get x=21 :D

next to find 1 just put 21 in place of x: 3(21)-3=60

since it's supplementary to angle 1 you take 180-60=120

angle <1=120!

D'Angelo bought two shirts at a special sale. He paid the full price of $19.99 for one shirt and got a second shirt of the same

Alex

Answer: $2.55

Step-by-step explanation:

He bought the second shirt for half off the first shirt's price. He therefore bought it at:

= 19.99/2

= $10.00

Total paid for both shirts is therefore:

= 19.99 + 10

= $29.99

Sales tax is 8.5% so he paid:

= 29.99 * 8.5%

= ‭2.54915‬

= $2.55

36 muffins is called yet Amelia will do 24.

Instead of multiplying 36, you will multiply 24 by 4.

24 × 4 = 96

She will need 96 cups of sugar to make 24 muffins.

The lengths of three sides of a triangle are given. Determine whether each triangle is a right triangle. 12 yd, 14 yd, 16 yd 15

bezimeni [28]

Given

sides of a triangles

Find

Determine whether each triangle is a right triangle.

Explanation

use the pythagoras theorem for right triangles.

According to the pythagoras theorem , the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the two legs of the triangle.

a) 12 yd, 14 yd, 16 yd

so ,

$\begin{gathered} 16^2=12^2+14^2 \\ 256=144+196 \\ 256\ne340 \end{gathered}$

hence it is not right triangle.

b) 15 km, 20 km, 25 km

$\begin{gathered} 25^2=20^2+15^2 \\ 625=400+225 \\ 625=625 \end{gathered}$

hence it is a right triangle.

c) 45 mm, 60 mm, 75 mm

$\begin{gathered} 75^2=45^2+60^2 \\ 5625=2025+3600 \\ 5625=5625 \end{gathered}$

hence it is a right triangle.

Final Answer

Hence ,

a) it is not right triangle

b) it is a right triangle

c) it is a right triangle
