Please help me and explain please

T = 7

Given the acute angle, m < 49°, and the right angle with a measure of 90°, and the angle with a measure of m < (5t + 6)°:

Since their sum add up to 180°, we can establish the following formula:

180° = (5t + 6)° + 90° + 49°

180° = 5t + 6 + 139°

180° = 5t + 145°

Subtract 145° from both sides:

180° - 145° = 5t + 145° - 145°

35° = 5t

Divide both sides by 5 to solve for t:

35°/5 = 5t/5

7° = t

Therefore, the value of t = 7°.

Verify whether we derived the correct answer by plugging in t = 7° into the equation:

180° = (5t + 6)° + 90° + 49°

180° = (5(7) + 6)° + 90° + 49°

180° = (35 + 6)° + 90° + 49°

180° = (41)° + 90° + 49°

180° = (41)° + 90° + 49°

180° = 180°

Therefore, t = 7° is the correct answer.
