Answer:
<h2>= 1.268</h2>
Step-by-step explanation:
= (3 + √3) (2 - √3)
= 6 - 3√3 + 2√3 - 3
= 3 - 3√3 + 2√3
= 3 - √3 (3 - 2)
= 3 - √3
= 3 - 1.732 ...... (√3 = 1.732)
= 1.268
Answer:
$19,720
Step-by-step explanation:
Put the given numbers into the formula and do the arithmetic.
P = principal amount, $17,000
r = interest rate, 8% = 0.08
t = 2 years
"I" = P + Prt
I = $17000 + $17000·0.08·2 = $17000 +2720
I = $19,720
_____
I put "I" in quotes because the variable capital-I is usually used in this context to refer to the amount of interest paid, not the entire repayment amount. However, that is what your formula is. It works for what you want.

Answer:
Step-by-step explanation:
ΔBCD is isosceles, so ∠CDB = ∠CBD = x. The sum of angles in the triangle is 180°, so you have ...
x + x + 50° = 180°
2x = 130° . . . . . . . . . subtract 50°, collect terms
x = 65° . . . . . . . divide by 2
__
Triangle ABC is also isosceles, so ∠BAC = ∠BCA = y. Angle ABC is the supplement of angle x. The sum of angles in ΔABC is 180°:
y + y + (180° -x) = 180°
2y - 65° = 0 . . . . . . . . . . subtract 180°, substitute the value of x
y -32.5° = 0 . . . . . . . divide by 2
y = 32.5° . . . . . . . . . . add 32.5°
