Every angle is the same so you know what the angle is because in one corner there is a 60 degrees since every angle is 60 degrees and one corner has 3x all you have to do is 60/3 to find x and 60/3 = 20 so x = 20

Answer:

x = 20

Step-by-step explanation:

The triangle is isosceles ( 2 congruent sides )

Hence the base angles are congruent, thus

3x = 60 ( divide both sides by 3 )

x = 20

Directions - For the following problem, write a paragraph proof to justify each step you make. All work must be neat,
nlexa [21]

$ PS = \frac{4}{3} x

Solution:

Given PRQ is a triangle.

ST is a line parallel to RQ.

$PT = x, \ PQ = 3x,  \ SR=\frac{8}{3}x

TQ=PQ-PT

TQ=3x -x=2x

<u>Triangle proportionality theorem,</u>

<em>If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.</em>

$\frac{PS}{SR} =\frac{PT}{TQ}

$\frac{PS}{\frac{8}{3} x} =\frac{x}{2x}

Do cross multiplication, we get

$ PS \times 2x=x \times \frac{8}{3} x

Divide by 2x on both sides, we get

$ PS = \frac{4}{3} x
