In ABC, if the lengths of sides a and c are 8 centimeters and 16 centimeters, respectively, and the measure of C is 35 degrees,

Simora [160]

Answer:

∠ A ≈ 16.67°

Step-by-step explanation:

Using the Sine rule in Δ ABC

$\frac{a}{sinA}$ = $\frac{c}{sinC}$ , substitute values

$\frac{8}{sinA}$ = $\frac{16}{sin35}$ ( cross- multiply )

16 sinA = 8 sin35° ( divide both sides by 16 )

sin A = $\frac{8sin35}{16}$ , thus

∠ A = $sin^{-1}$ ( $\frac{8sin35}{16}$ ) ≈ 16.67° ( to 2 dec. places )

I need help with this one too I’m marking brilliant

alukav5142 [94]

Answer:

Step-by-step explanation:

For this problem, I basically solved each equation until it agreed with the sequence.

It's not A or C because when you plug in 1, the number doesn't equal 3.

a = 2(-3)¹⁻¹ = 2(-3)⁰ = 2(1) = 0

a = 3(-2)¹ = -6

It's not D because when you plug in 2, the number doesn't equal -6.

a = 3(2)²⁻¹ = 3(2)¹ = 6

Please help me ASAP!!

I don't like these computer choice thingies. It detracts from the math.

$-x - 2y = 7$

$5x - 6y = -3$

If we want to eliminate x we multiply the first equation by 5 then add it to the second:

$-5x - 10y = 35$

$5x - 6y + (-5x - 10y) = -3 + 35$

$-16y = 32$

OK, that's how it's done. Reading through the choices, that's choice D.
