1) m<DCB = <D + <C + <B
180 = 25 + 90 + <C (Angle Sum Property)
180 = 115 + <C
180 - 115 = <C
65 = <C
4 x 27 = 108 and 4 + 27 = 31... I don't think there is any pair of numbers that would equal -31. So the answer would be 4 and 27. Good luck! Hope this helped!!
Answer:
x = 12
Step-by-step explanation:
Solve for x:
(3 x)/4 = 9
Multiply both sides of (3 x)/4 = 9 by 4/3:
(4×3 x)/(3×4) = 4/3×9
4/3×3/4 = (4×3)/(3×4):
(4×3)/(3×4) x = 4/3×9
4/3×9 = (4×9)/3:
(4×3 x)/(3×4) = (4×9)/3
(4×3 x)/(3×4) = (3×4)/(3×4)×x = x:
x = (4×9)/3
9/3 = (3×3)/3 = 3:
x = 4×3
4×3 = 12:
Answer: x = 12
