Given that the two triangles are similar, solve for x if AU = 20x + 108, UB = 273, BC = 703, UV = 444, AV = 372 and AC = 589.

The answer:
the two triangles are similar
in addition, the line UV is parallel to line BC, so we can use the theorem of Thales for proving the following ratios:

AV /AC = AU/ AB= UV/ BC
372/589=20x +80 / AB = 444 / 703

so we get (372/589) AB - 80 = 20x, and x = ( (372/589) AB - 80 ) / 20

exact value of x depends on the value of AB

I never learned this. I tried I just don’t understand. Can anyone help

Answer:

Step-by-step explanation:

n = 25

33+n = 33+25 = 58

n/5 = 25/5 = 5

$\sqrt{n+144}=\sqrt{25+144}=\sqrt{169}=13$

Can a triangle be drawn with the following angle measures? Why or why not? 50°, 70°, 70°

Viefleur [7K]

no, the 3 angles of a triangle need to equal 180 degrees

70 +70 +50 = 190 degrees so it cant be a triangle.

Find the 59th term of the arithmetic sequence 29,37,45,...

liberstina [14]

Answer:

13,456

Step-by-step explanation:

Tn= a+(n-1)d

a is the first term, n is the given number and d is the common difference. d is given by subtracting the first term from the second term or the second from the third. Therefore the the 59th term of the sequence 29, 37, 45 is,

Tn= 29+(59-1)8

=29(58)8

=13,456

Could you pls teach me this question

Alexandra [31]

Answer:

if it's area the area would be the length of the diameter of the semi circle which is the height of the triangle multiplied by the base of the triangle to find the area of the triangle then to find the area of the circle would be pie multiplied by the diameter divided by two squared

$\pi \ \times 7 {}^{2}$

then the total area would be the area of the triangle plus the area of the half circle
