Answer:
71°
Step-by-step explanation:
BDH is a triangle (as seen on figure)
<BDH + <DBH = <DHE ( Sum of two interior angles of a triangle is equal to the opposite exterior angle)
40° + 31° = X
X = 71°
Answer:
Right triangle
Step-by-step explanation:
Using pythagorean theorem,

Hence satisfied. So it is right triangle.
Answer:
see explanation
Step-by-step explanation:
(a)
Given
x² + 5x + 6
Consider the factors of the constant term ( + 6) which sum to give the coefficient of the x- term ( + 5)
The factors are 3 and 2, since
3 × 2 = 6 and 3 + 2 = 5, hence
x² + 5x + 6 = (x + 3)(x + 2) ← in factored form
(b)
To solve
x² + 5x + 6 = 0 ← use the factored form, that is
(x + 3)(x + 2) = 0
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x + 2 = 0 ⇒ x = - 2
Answer:
Step-by-step explanation:
$3000 * 0.04 = $120
$100 * 0.02 = $20
total 2 accounts = $120 + $20 = $140
answer: $3000 was the originally deposited into the account that pays 4% interest.
Answer:
The answer is A. $421.29
Step-by-step explanation:
Just keep finding 19% of the numbers next, and you add that all up and you get the answer.
250 x 19%=47.5. (250+47.5)=> 297.5x19%= 56.525. (297.5+56.525) =>354.025x19%=67.26475
354.025+67.26475=> 421.28975, which can round up to 421.29.
