The bottom left angle is 180 -80=(100)
So the remaining 2 angles are equal 80
As all angles in a triangle are equal to 180
X+5 + x - 5 =80
Simplify
2x=80
X=40
Soo one of the angles are 40-5 which is (35)
And the other is 40+5 which is (45)
So sean is not correct
~sorry sean teehee
Answer:
18
Step-by-step explanation:
32.25-9.85
22.5/1.25
18
1/2
If ABC ~ DEF then 12/6, 16/8, and 18/9 would equal 2
BUT since we are going from a large triangle to a small triangle, our answer needs to be less then one, making our answer 1/2
Your answers:
10) (m+7)(m+8) 11) (b-10)(b+2)
12) (k-4)(k+10) 13) (n-9)(n-8)
14) (7r+3)(r-2) 15) (5a+6)(a+2)
Hope it helps
