If a = 4 ft, c = 13 ft, and m∠B = 17°, what is the approximate area of ABC?

Answers

Answer:

7.6 ft² ( to 1 dec. place )

Step-by-step explanation:

given 2 sides of a triangle and the angle between them, the area (A) is calculated using the formula

A = $(1)/(2)$ ac sin B

= 0.5 × 4 × 13 × sin 17° ≈ 7.6

the difference between two numbers is 9. the first number plus twice the other number is 27. find the two numbers

Answers

So,

Let's translate this into mathematical form.

x - y = 9
x + 2y = 27

Elimination by Addition
Divide both sides of the second equation by 2
$(1)/(2)x + y = 13 (1)/(2)$

Add the two equations together
$(3)/(2) x = (45)/(2)$

Multiply both sides by $(2)/(3)$
$x = (90)/(6) \ or \ 15$

Substitute
15 - y = 9

Subtract 15 from both sides
-y = -6
y = 6

Substitute
15 - 6 = 9
9 = 9 This checks.

15 + 2(6) = 27

Distribute
15 + 12 = 27
27 = 27 This also checks.

S = {(15,6)}

a-b=9 ......a=9+b
a+2b=27
(9+b)+2b=27
9+3b=27
3b=27-9
3b=18
b=6
a=9+b=6+9=15
