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°

Answer:they are all straight across so drag each line to the one that is across from the equation
Step-by-step explanation:
100+30=130
100+40=140
online price is 130% or original
superstore price is 140% or original
the difference bewteen them is 140-130=10% of the original price
A. 1.3 times 160=208=online
1.4 times 160=224=superstore
B. difference is 224-208=16=10% of 160
it is 10% of the original price
A. online=$208
superstore=$224
B. $16, this is 10% of the original price
