Question

*The two angles of a right triangle are 90 degrees and 60 degrees, what is the measure of the remaining angle?* 1️⃣ 150° 2️⃣ 30° 3️⃣ 120° 4️⃣ 180°​

Answer 1

Answer:

2. 30 degrees

because sum of all angles in triangle should be 180 degrees

90+60=150

180-150=30

Answer 2

Answer :

(2) 30°

Given :

• Two angles of a right triangle are 90 degrees and 60 degrees.

To find :

• the measure of remaining angle.

Solution :

⇒ Let's find the remaining angle.

→ Sum of one right-angle triangle = 90°

∴ Sum of two right-angle triangles = 90° × 2

= 180°

• Let the remaining angle be x.

→ 180° = x + 90° + 60°

→ 180° = x + 150°

→ x = 180° - 150°

→ x = 30°

∴ x = 30°

• Therefore, the remaining angle is (2) 30°.
