No, because first of all 125 +36 + 24 should equal 180° not 185° because the area of a triangle always has an area of 180. Second, you don't even have to calculate anything because an isosceles triangle has two measures that are the same °∞° Hope this helps!
Answer:
a = 63˚
Step-by-step explanation:
1. Recognize that any triangle = ∑180˚
2. 180-81-b-a=0
3. 180-117=63˚
Answer:
20%
Step-by-step explanation:
70/350 = 0.2
0.2 x 100 = 20%
35,725
this is because u can take the ratio 7+5+9=21 then take 150,045/21 which u get 7,145 then time 5 and u get 35,725
X+4+3x =
4x+4 (you sum the like terms )
