Answer: isosceles

Step-by-step explanation:

By the alternate interior angles theorem, \angle CAB=50^{\circ}

Since angles in a triangle add to 180 degrees, \angle ACB=180^{\circ}-80^{\circ}-50^{\circ}=50^{\circ}

Since sides opposite equal angles in a triangle are equal, AB=BC.

So, triangle ABC is <u>isosceles</u>

Greeley [361]

Answer:

A = $1311 and 96cents

Step-by-step explanation:

A = P(1 + \frac{r}{n})^{nt}

P = $1200

r = 1.8% = 0.018

n = 1 (compounded yearly)

t = 5

A = 1200(1 + 0.018)^5 = 1200 \times(1.018)^5 = 1311. 96
