0.8x + 2.71 = 1.898 - 0.6x
Add 0.6x to each side.
0.6x + 0.8x + 2.71 = 1.898 - 0.6x + 0.6x
1.4x + 2.71 = 1.898
Subtract 2.71 from both sides.
-2.71 + 1.4x + 2.71 = 1.898 - 2.71
1.4x = -0.812
____=_____
1.4 = 1.4
Divide by 1.4
x = -0.58
Hope I helped
X = length of shortest side
Therefore the remaining sides will be x +2 and x + 7
x + x + 2 + x +7 = 45
3x + 9 = 45
3x = 36
x = 12
x + 2 = 14
x + 7 = 19
The sides are 12, 14, and 19 cm. long. Hope this helped!
C, because if it was D, they would be the same, which is A written in another format. Then process of elimination
angle D = 92°
Step-by-step explanation:
Since the two figures are congruent.
angle D = angle K
20x + 12 = 25x - 8
5x = 20
x = 4
Substituting this value into angle D, we see that
angle D = 20x + 12
= 20(4) + 12
= 92°
