Find the desired missing angle:
59°
?
78°


Find The Desired Missing Angle 59 78 class=

Sagot :

It’s a triangle
In a triangle the total of all the angles is 180 therefore do this working
59 + 78 + x(unknown) = 180
137+x=180
x=180-137
x=43

The missing angle is 43

The desired missing angle is 43°

What is the right triangle?

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

What is Pythagoras theorem?

Pythagoras theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

Let the missing angle would be x

We have to determine the missing angle.

Since the total of all the angles is 180 degrees in a triangle.

⇒ 59° + 78° + x = 180°

⇒ 137° + x = 180°

⇒ x = 180 - 137

Apply the subtraction operation,

⇒ x = 43°

Therefore, the desired missing angle is 43°
