Answer:
x = 21, m∠A = 23°, the measure of angle in the right = 67°
Step-by-step explanation:
The angles of a triangle sum up to 180°.
Right angles equals to 90°.
Thus, (2x - 19)° + (3x + 4)° + 90° = 180°
=> 5x + 75 = 180
=> 5x = 105
=> x = 21
m∠A=> 2(21) -19 = 23°
the measure of angle in the right=> 3(21) + 4 = 67°
Step-by-step explanation:
(A)It says AT A BASKETBALL CHAMPIONSHIP so obviously most people there would’ve said basketball.
(B) Maybe try doing the whole school and not just the students at the basketball championship.
hope this helped! if you need anything else let me know. <3
