Step-by-step explanation:

Use SOH-CAH-TOA.

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

Side a is adjacent to the 29° angle, and 14 is opposite of the 29° angle. So use tangent:

tan 29° = 14 / a

a = 14 / tan 29°

a ≈ 25.3

Side c is the hypotenuse, and 14 is opposite of the 29° angle. So use sine:

sin 29° = 14 / c

c = 14 / sin 29°

c ≈ 28.9

Select the expression that has a value of 96.45

leonid [27]

Given:

Number is 96.45.

To find:

The expression that has a value of 96.45.

Solution:

In option a,

$0.9645\times 10^2=0.9645\times 100$

$0.9645\times 10^2=96.45$

In option b,

$9.645\div 10^1=\dfrac{9.645}{10}$

$9.645\div 10^1=0.9645\neq 96.45$

In option c,

$964.5\times 10^3=964.5\times 1000$

$964.5\times 10^3=964500\neq 96.45$

In option d,

$9645\div 10^3=\dfrac{9645}{1000}$

$9645\div 10^3=9.645\neq 96.45$

Therefore, the correct option is a.
