I also agree that the answers is the second one have a beautiful day:)
-t=9(t-10)
-t=9t-90
90=9t+t
90=10t
90/10=t
9=t
Answer:
base = 5.6 cm
Step-by-step explanation:
area of a triangle = 1/2 * base * height
area = 5.88 cm²
height = 2.1 cm
5.88 = 1/2 * base * 2.1
5.88 = 1.05 base
5.88 / 1.05 = base
base = 5.6 cm
