First Question

A triangle with 3 congruent (equal) sides is defined as an equilateral triangle. Scalene triangles have no equal sides, isosceles have 2 equal sides, and right triangles have a 90-degree angle.

Step1: Identify given values

$P = 1000$, $r = 0.04$, $t = 10$

Step2: Substitute into compound interest formula

$A = 1000(1+0.04)^{10}$

Step3: Calculate $(1.04)^{10}$

$(1.04)^{10} \approx 1.48024$

Step4: Compute final amount

$A = 1000 \times 1.48024 \approx 1428.24$

Answer:

a. Equilateral
