Answer: the scale factor is 2.5
Step-by-step explanation: hope it helps :)
12 divided by 10 is 1.2. 15 multiplied by 1.2 is 18 so x equals 18
Idk but it can't be 10 or 9.7 bc a triangle's hypotenuse is always longer than its legs
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°
