Solve for x.
6
-10
7
-9

x=7

Step-by-step explanation:

The triangle is right angled meaning that one of the angles is 90⁰.

90+30+(9x-3)=180 (Angle sum property of a triangle)

120+9x-3=180

9x-3=180-120

9x-3=60

9x=60+3

x=63/9

x=7

The angle will be (9×7)-3=60⁰

factor trees are nice.

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
