Since the three interior angles of a triangle add up to 180 degrees you can always calculate the third angle like this: Let's suppose that you know a triangle has angles 90 and 50 and you want to know …
WebQ1) Find the unknown angles in the given figures: Answer: Solution: (i) In Fig (i), x = y (Angles opposite to equal sides) But x + y + 80° = 180° (Angles of a triangle) ⇒ x + x + 80° = 180° ⇒ 2x = 180° - 80° = 100° ⇒ x = 100°/2 = 50° ∴ y = x = 50° Hence x = 50°, y = 50° (ii) In Fig. (ii), b = 40° (Angles opposite to equal sides) WebAug 14, 2024 · To find an unknown angle measure, sometimes it is helpful to write and solve an equation that represents the situation. For example, suppose we want to know the value of \(x\) in this diagram. Figure \(\PageIndex{12}\) Using what we know about vertical angles, we can write the equation \(3x+90=144\) to represent this situation.
