Question

Can somebody solve them and explain to me. I'M LOST?!

Answer 1

Answer:1. The measure of angle P is 53.  2. The value of x is 25.

3. The length of each side of the triangle is 30 cm.

Step-by-step explanation:

1. (3x +2) + (3x + 2 ) + (5x -11) =180  Angle Q and P have the same measures because it is an isosceles triangle that is why you have three expressions.

So x =17   and 3(17)+ 2 =53

2. (2x +10) + (2x+10) + (2x + 10)= 180 this is because the second triangle is an equilateral triangle which means all it have the same measures.

solve for x. and x  is 25.

3.The third triangle is also an equilateral triangle so you will make the expressions equal each other and solve for y .

1/10y + 11= 3/5y -4

y= 30
