Find the indicated side of the triangle

The indicated side of the triangle is 14

Step-by-step explanation:

Given

A Right angled triangle with angle of 30°

Let the angle be represented by θ

i.e. θ = 30°

The side facing/opposite θ is referred to as opposite.

Let Opp represent opposite

Opp = 7

The hypothenus of the triangle is represented by a

To calculate length a, we make use of the relationship between θ and the sides of the triangle.

Provided that the length of the opposite side of the triangle is known and the missing length is the hypothenus, we can make use of sin(θ) to solve this.

Sin(θ) is calculated by Opposite ÷ Hypothenus

i.e.

Sin(θ) = Opposite/Hypothenus

Substitute known values

Sin(30) =7/a

Make a the subject of formula

a * sin(30) =7

a = 7/sin(30)

sin(30) = ½

So, a = 7/½

a = 7 * 2

a = 14

Hence, the indicated side of the triangle is 14

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200
