find the value of x. if necessary, you may learn what the markings on a figure indicate.
Answer
Explanation:
Step1: Identify triangle - type
The right - hand triangle is equilateral since all its sides are marked equal. So all its angles are 60°.
Step2: Use angle - sum property of large triangle
The large triangle has one angle of 33° and an angle from the equilateral triangle which is 60°. Let the third angle be (x). The sum of angles in a triangle is 180°. So (x=180-(33 + 60)).
Step3: Calculate (x)
[x=180-(33 + 60)=180 - 93=87]
Answer:
87
