Find a (geometry) plz help

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.

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

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

We get a to be:

14

a is equal to 14

Btw you look cute in that picture you took

a = 14

Step-by-step explanation:

we know,

sin 30° = 1/2

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

so,

equating both equations we get,

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
