Question

Find a (geometry) plz help

Answer 1

Answer:

a = 14

Step-by-step explanation:

we know,

sin 30° = 1/2

sin 30° = 7 / a ( perpendicular / hypotenuse )

so,

equating both equations we get,

=》

$\frac{1}{2} = \frac{7}{a}$

=》

$a = 7 \times 2$

=》

$a = 14$

i hope it helped...

Answer 2

Answer and Step-by-step explanation:

We are given:

A side length of 7

An angle of 30.

We will use trigonometric functions to solve for a.

We will use the sine trig function.

$sin(Angle) = \frac{Opposite (Side)}{Hypotenuse (Side)}$

$sin30 = \frac{7}{a}$

Multiply a by both sides, then divide by sin30 on both sides.

$a = \frac{7}{sin30}$

Now, use a calculator and do 7 divided by sin of 30.

We get a to be:

14

a is equal to 14
