The number I believe you are looking for would be an exact form of -28/9
Or a decimal form would be -3.1 repeating
(1/2(AC) * DC) / (1/2(BC) * DC) = 3/4
AC / BC = 3/4
The coordinate of C be (x, y), then
((4(1) + 3(8))/7, (4(-9) + 3(-2))/7) = ((4 + 24)/7, (-36 - 6)/7) = (28/7, -42/7) = (4, -6)
X = 7
The angles are congruent so you’d do, 4x-5=23 and you’d get x = 7
Answer:
160
Step-by-step explanation:
Rectangle = 10x15=150
Triangle = 1/2x5x4=10
150+10=160
