If the two angles of the triangle are equal. Well yes, because if the angles are both 50 degrees then the other angle will be 30. but it also depends on the shape of the triangle if they differ.

True.

The sum of angles in a triangle is equal to 180 degrees. If two of the angles are equal to two of another, then it means the third angles are also equal.

The third angle for each triangle must be = 180 - (Sum of the two)

So all the three angles of one triangle is equal to the three of the second.

Therefore the two triangles are similar.

But they might not have exactly the same size, one might be bigger in shape than the other, but they must look alike, because the three angles of each are the same to the other.

What is the equation of the line that is parallel to the line defined by the equation y = 3x + 6 and goes through the point (3,
saw5 [17]

Answer:

Step-by-step explanation:

Parallel lines have the same slope. The slope of the given line is 3. The easy way to do this, the one that uses our logical brains as opposed to our mathematical brain, tells us that since there is only one choice that has a given slope of 3, that is the one that we want. The second choice down is the only one that has a slope of 3.

Mathematically,

y-2=3(x-3) and

y-2=3x=9 and

y=3x-9+2 so

y = 3x - 7 (the second choice)

You are out bottle caps, and decide to use Popsicle sticks instead. You measure them, and they are 15.2 cm tall. How many Popsic
satela [25.4K]
It depends on how many Popsicle sticks you are going to use.So, for example, say that you are using 5 Popsicle sticks for the model. What you do is 15.2 x 5, 15.2 being the height of the sticks and 5 for the number of sticks you are using. The answer will be 76 cm tall.           21                                                                                                                     15.2                                                                                                               x    5                                                                                                                ---------                                                                                                             76.0

Can someone please help me with this question? Thank you!
Goryan [66]

Answer: A

<u>Step-by-step explanation:</u>

\stackrel\frown{XY} ≅ \stackrel\frown{YZ}

⇒ ∠XOY ≅ ∠ZOY

\overline{XO} ≅ \overline{ZO} since they are both a radius

\overline{OY} ≅ \overline{OY} based on reflexive property

∴ ΔXOY ≅ ΔZOY by SAS

So, \overline{XY} ≅ \overline{ZY} by CPCTC

ZY = 10.2 is given

so, XY = 10.2 by substitution property

49.5 is what percent of 33
Svet_ta [14]



  49.5 over 33 and X over 100 cross multiply so multiply 33 by x you get 33x then multiply 100 by 49.5 you get 4,950 then divide 4,950 by whatever is in front of X so 33 4,950 divided by 33 equals 150%
49.5/33   X/100   49.5x100= 4,950    33* x = 33x  4,950/33=150
