First you need to know that the internal angles of a triangle always equals 180°. Therefore:
15+45= 90°
Then since the angles should equal 180, you do:
180-90=90
So the missing angle equals 90°
Answer:
90 degrees
Step-by-step explanation:
its a 45-45-90 triangle
Answer:66
Step-by-step explanation:
Y=mx+b
10=-4*12+b
10=-48+b
b=58
r=-4(-2)+58
r=66
