In right △abc with right angle b, m∠a=(3x−8)° and m∠c=(x−2)°. what is m∠a? question options: 47° 67° 25° 92

Option 2nd is correct

67°

Step-by-step explanation:

Given that:

In right △ABC with right angle B.

, m∠A=(3x−8)° and m∠C=(x−2)°.

We know that the sum of all the measures of a triangle is 180 degree

In triangle ABC

⇒

Substitute the values we have;

Subtract 90 degree from both sides we have;

Combine like terms;

Add 10 to both sides we have;

Divide both sides by 4 we have;

then;

m∠A=(3(25)−8)° = (75-8)° = 67°

Therefore, the measure of angle A is, 67°
