A) (4x1)+(9/10)
B) (10x1)+(4x1)+(5/100)
C) (2x1)+(2/10)+(2/100)
Answer:
The answer is D, (0, -3)
Step-by-step explanation:
The solution of a system is where the two equation intersect which each other.
2l+2w=876
3w-1=l
Sub in l to find w
2(3w-1)+2w=876
6w-2+2w=876
8w=876+2
8w=878
W=109.75
Sub in w to find l
3(109.75)-1=l
329.25-1=l
L=328.25
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
