Answer:
In a right triangle, one angle should be a right angle, which means that angle should be 90°. Right angles are always 90°.
And in any triangle, the sum of the 3 interior angles should add up to 180°, this rule is always the same. Therefore, to find the third angle, we should simply subtract the angles we already know from the angle sum of triangle.
We can therefore list this equation:
Third angle = 180° - 24° - 90°
Third angle = 66°
Your answer should be 66°
2) Explanation:
The sum of the 3 angles in a triangle is 180∘here we have 2 angles of size 90∘and 51∘⇒third angle=180−(90+51)=180−141=39∘
Explanation:
Answer:
∠A = 104
Explanation:
Triangles are equal to 180° so if one angle is 38° and the other angel is equal to 38°, then the third angle must make each of those angles add up to 180.If you add 38 + 38 and subtract the sum from 180 you will get the measurement of angle A (38 + 38) - 180 = 104
