Answer:
x= 20
Step-by-step explanation:
The sum of the three angles is 90 degrees
x+2x+x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10
4x+10-10 = 90-10
4x= 80
Divide by 4
4x/4=80/4
x = 20

By 10s, 100s, 5s, 15s, 20s, 30s,
Answer:
Obtuse
Step-by-step explanation:
Plugging the numbers into the Pythagorean Theorem (a^2 + b^2 = c ^2)
20^2 = 12^2 + 15^2
400 > 144 + 225
400 > 369
Because of the Converse of the Pythagorean Theorem, which tells us if c is greater than a+b, it is obtuse
