<span>We have to find the value of x if the measures of the angles of a triangle are: 2 x, 3 x and 4 x. We know that the sum of the measures of the angles of a triangle is 180 degrees. A + B + C = 180. Here we have: A = 2 x, B = 3 x and C = 4 x; 2 x + 3 x + 4 x = 180; 9 x = 180; x = 180 : 9. Answer: x = 20 degrees.</span>

Salsk061 [2.6K]

Answer:

   Trevor has 16 number of shirts

Step-by-step explanation:

We have been given that Trevor and Marisa together have 28 t shirts to sell if Marissa has 4 fewer t shirts than Trevor

let the number of shirts Trevor have be x

And since, Marissa has 4 fewer than Trevor so number of shirts Marissa will have be x-4

Hence, according to question equation becomes:

x+x-4=28

We will solve for x to find the number of t shirts  Trevor has

2x -4 =28

2x = 32

x =16

Hence, Trevor has 16 number of shirts

Find the value of z in the figure below.<br>.​
zzz [600]

answer

z = 100

opposite angles

when inscribed in a circle, the opposite angles of a quadrilateral add up to 180

so z + 80 = 180 and y + 120 = 180

solve for z

z + 80 = 180

z = 180 - 80

z = 100
