Divide both numbers by 13/90
13/90x = 130
÷13/90 ÷13/90
x= 900
2 graph I think not certain
Uhh, these give me a headache, I think number 2 is array..
SO you know that triangles add up to 180. A right angle equals 90 so 180-90=90. And an isosceles triangle means that 2 angles are congruent. SO 90/2 = 45. The measure of the 2 acute angles are 45
